Here’s 23 tips for new Jayco camper trailer owners

(plus some answers to a few of the most frequently asked questions)

These are things that are specific to the operation of a windup camper trailer…

…and are things I wish I knew when we first got our Jayco Swan.

Here we go:

1. Hang the upper part of the door flat against the ceiling

How you hang the top part of the door makes a BIG difference when you wind down the roof of your camper.

This was a mistake we made:

If you leave the door hanging down at the entrance when you attach the little clips…

Hanging Jayco Camper Trailer Door on Roof Incorrectly

…then it can get in the way when you lower the roof.

This can make the lid hard to close, or even bend the clips.

But if you push the metal plate up first?

The door folds flat to the roof:

Tip - Hang Jayco Camper Trailer Door Flat on Roof

This makes the roof easier to close and gives more space for bedding

(and lets us keep our Ever Rest Memory Foam mattress topper on the bed when we pack down)

2. Check your roof safety switch if your lights aren’t working

A question that pops up nearly every day:

Why aren’t my Jayco camper’s lights working even though I have power everywhere else?

There’s a roof safety kill switch whose job is to cut power to the roof when it’s packed down

Jayco Camper Roof Safety Switch

(so if the lights are accidentally left on they don’t melt the canvas or cause a fire)

The most common reason the lights aren’t working:

The switch often malfunctions because the metal lever gets caught and doesn’t let the white button drop down

So you might just need to check it here:

Jayco Camper Roof Safety Switch - Metal Tongue Missing or Removed

(on our Jayco Swan the metal lever has fallen off the switch at some point)

Believe it or not, cutting it out and simply joining the wires is one of the 35 Most Popular Jayco Camper Trailer Modifications

[because if you’ve turned off all the switches and/or disconnected the power before lowering the roof then there’s no power supply anyway]

Also, check that the 12 V plug near the sink is seated correctly too… and not corroded

3. Check the telescopic arms have lifted while you’re winding up the roof of your camper

Sometimes when you’re winding up the roof of your Jayco camper trailer the middle telescopic arm doesn’t slide freely.

This can cause one of the lifting arms to pop out and really ruin your holiday.

So when you’re winding up the roof of your camper it’s wise to stop half to three-quarters of the way and check the lifters

[It’s a step in our Jayco Camper Trailer Set-Up Checklist]

If the main outer sleeve looks like this:

Telescopic Sleeve Caught on Jayco Swan Camper Trailer

Gently slide it up with your hand so it looks like this:

Jayco Swan Camper Trailer Tip - Push Up The Telescopic Sleeve

But… it’s important you find out WHY this is happening:

Unless the lifter arms are bent it’s usually that the arms need to be sprayed with some silicon spray

(or that the camper isn’t levelled properly)

HINT: The Velcro covers  are there to keep your lifter arms clean and dry

[you’ll see what I mean in Number 6]

4. Cool down your 3-way fridge well before you need it

The 3-way fridge in a Jayco camper is pretty much designed to be run on:

  • Gas when you’re free camping
  • 12V from your car when you’re driving
  • 240V when you have access to mains power

It takes about 24 hours for your fridge to cool down…

Should you run the fridge on 240V with the roof of a Jayco camper trailer wound down?

Some people have been doing it for years with no problem and say it depends on the van:

  1. If it’s an older model that has venting in the top of the bench then ‘no’
  2. If it’s vented outside then it’s fine

But… even on our 2014 Jayco Swan OB (vented outside) it still has this warning:

Jayco Swan Tip - Do Not Operate Fridge on 240V When Roof Down

This might be some good ol’ fashion butt covering…

…but then there’s this Jayco Penguin that was for sale for parts:

Jayco Penguin Camper Trailer Fridge Fire

Maybe it would have happened anyway even if the roof was up?

Anyway… to make sure you can keep your camping supplies cool when you reach your destination a couple of options are:

  1. Put some pre-frozen bottles of water in the fridge to cool it down while you’re travelling (and take things in an esky), or
  2. Plug your camper into 240V a day or two before you travel

(we don’t have a 15A power point installed so we got one of these Ampfibian 15A to 10A adaptors from eBay)

If I can’t set up our Jayco Swan before travelling, I’ll stick with the first option

5. Always make sure your camper is level before you set up

There was this one time (before I fixed a T-spirit level to our drawbar) that I set up our Jayco Swan and it wasn’t level:

The door wouldn’t shut properly.

Water pooled on the sink.

But the big one?

The roof was noticeably leaning to one side

(the whole time I was worrying that it would bend the telescopic lifter arms)

And… not having a 3-way fridge level can stop it from working properly.

Sticking a T-spirit level on the drawbar is the best $5 you’ll ever spend on your camper

HINT: Don’t stick it straight on there… just because your drawbar is level, doesn’t mean your bench or sink will be too

6. Use roof support poles (but as backups only)

A pair of roof support poles now come as standard when you buy a Jayco camper trailer:

They’re like 1200 mm insurance policies in case your roof collapses.

If your camper didn’t come with (at least) 2 of these then grab a pair for the corners opposite to the door and wardrobe

Jayco Camper Trailer Tips - Use Bed Support Poles and Velcro Covers

But remember:

There’s no designated weight-bearing area in the roof for these poles. They’re a fail-safe only. Don’t take tension off the lifting arms and rest the roof on the poles.

Ours came with 4 and take less than a minute to put in

(I do it while I’m checking the sleeves are fully up and when I’m closing the Velcro).

You can get them yourselves with some aluminium poles and rubber stoppers from Bunnings.

But to be honest?

By the time you’ve bought all of that it’d be just as cheap to buy them from your local Jayco store

[they’re about $12.50 each]

Fun fact:

I scrounged the Internet and could only find one single example of the roof collapsing once it’s up. Collapses seem to occur during set-up…

7. Double check that the roof clips are undone before you start winding up the roof of your camper

One of the most common causes of cable failure is forgetting to undo one of the catches and starting to wind up the roof.

Even if it doesn’t fail now, it can start to open up the eye bolts that hold the cable

Jayco Camper Trailer Eyebolt - Opening Up

(they’re an engineered weak point)

I’ve given myself this gentle reminder:

Jayco Swan Camper Trailer Tip - Check All Roof Clips Are Undone Before Winding

8. Keep slack off the cables when the roof is down

When you’re winding down the roof of a Jayco camper it’ll usually stop a couple of centimetres off being completely closed.

Resist the temptation to keep unwinding because the cables will get slack in them

(and may not spool properly when you go to wind it up again)

Use the clips to close the roof… and give the handle a GENTLE turn to take any slack off the cable

9. Do the bed end fly mod (so you’ll use them more often)

I thought the bed and flys would be something I’d only use in bad weather.

Jayco Swan Camper Trailer Bed End Fly Modification

But I’ve since come across some reasons to use them (nearly) every time I set up.

There’s probably more, but here’s…

9 reasons to use bed end flys on your Jayco camper trailer:

  1. They keep your van a bit darker in the mornings (important with small kids!)
  2. Creates more privacy if your windows are open
  3. Stops condensation landing directly on your bed ends on cold and damp nights
  4. Keeps your bedding dry during pack up
  5. You can stand under them to keep your bed dry while you’re setting up
  6. Keeps the sun off the bed ends to keep them cooler
  7. They create an air gap for extra insulation
  8. Stops rain from landing and pooling on your bed ends
  9. No folding bird poo into your bedding!

Our Jayco Swan came with these CampSmart ones

(we love them)

Sure, they’re one extra thing to do during set-up and pack-up, but they’re worth it.

Want to make the bed end flys quicker to set-up, with less poles, and less  guy ropes to trip over?

Then check out the bed fly conversion kit from SupaPeg via eBay

(about $40 and one kit does both ends)

10. Insert the hockey sticks before doing up the Velcro on your bed ends

Plastic Bed Saddles for Jayco Swan Camper Trailer - Round Bracket for Hockey Stick

If you fasten the Velcro on your bed ends before inserting the the hockey sticks, then this:

  • Makes it harder than it needs to be, and
  • Can snap off the round bit on the Plastic Bed Saddles

Jayco Camper Trailer Hockey Stick Plastic Bed Saddle

(we carry spares a couple of spares, they’re about $7 here on eBay)

Our set-up routine is pull out the beds, go inside to insert the hockey stick, then go back out to do up the Velcro.

11. Create a checklist of things to do before you lower the roof

There’s some things that are a pain in the bum if you forget to do before you lower the roof.

If you forget to switch the fridge over it won’t work while you’re driving.

Or worse:

If you forget to turn off the lights it can cause a fire.

Fire From Leaving Lights Plugged in When Roof of Jayco Camper Trailer Roof Down

Full credit to the person we bought our Swan from…. they made this handy laminated list for the inside of our door:

  • TV antenna
  • Light plug
  • Fridge
  • Battery switch
  • Door
  • All power switches

(I was surprised that ‘door’ was on this list… until one day I went to wind down the roof without doing it too!)

12. Lubrication is your friend

Unlike a caravan, a Jayco camper trailer has a lot of moving parts…

…so it’s important you keep things well lubricated to reduce wear, tear, and effort.

A can of this stuff is less than $10 from Bunnings:

WD-40 Silicon Spray for Jayco Swan Camper Trailer Telescopic Lifter Arms and Bed Rollers

The first time I used it I noticed a massive difference in:

  • Opening and closing the zips on the bed and flys
  • Sliding the beds in and out
  • Letting the sleeves on the telescopic lifter arms move more freely

HINT: Hold a piece of cardboard behind the lifter arms when you spray so you don’t stain the canvas

13. Keep your canvas as dry as possible

Anyone who’s owned a camper trailer before knows that you should:

  1. Try to let your camper dry out as much as possible before packing up
  2. If you have to pack up when it’s wet, set it up at home and let it dry out
  3. Open it up regularly to make sure there’s no moisture trapped inside

(it’s easy to kill mould, but removing mould stains is another story)

One of the things about a Jayco camper trailer is that there’s still air circulating even when it is closed down.

Moisture absorbers are only a couple of dollars…

…get them from hardware stores, cheap shops, and most supermarkets

(you’ll be surprised how quick they fill up)

14. Turn the battery switch on when you’re on 240V to charge your battery properly

Your battery will not charge properly if you’re plugged into 240V and the battery switch is off.

Depending on the model of Setec charger that’s in your Jayco camper leaving the switch off will either give:

  1. Trickle charge at 0.8A, or
  2. No power at all

If you have access to 240V… both Setec Series II and Series III manuals say the same thing:

SETEC Battery Charger - Turn Swith On To Charge Battery

Turning it on allows it to use its 4 modes:

  • Boost
  • Float
  • Store, and
  • Trickle

SETEC Battery Charger - Turn Swith On To Charge Battery and Extend Life

This extends the battery life. During store mode, the unit exits to boost mode for 15 minutes every 24hrs to maintain charge in the battery.

And if you can’t (or don’t want to) leave it plugged in?

Jayco Camper Trailer Tips - Connect Battery For 2-5 Days Before Camping

Leave the power supply on for at least 2 – 5 days with battery connected

NOTE: If you’ve got something different to a Setec charger (like a BMPro) then turning off the switch may have no impact on the charger

15. Fold the canvas flat to make it easier to close your roof

If the canvas is all bunched up on the mattresses then:

  • It creates more bulk, and
  • Air pockets can get trapped

[this can make the difference between keeping your bed made or leaving a mattress topper in place]

To get things as flat as possible the method that works for us is to:

  1. Push the rear bed in first
  2. Go inside to pull the rear canvas flat
  3. Fold the front canvas using the “envelope” method

How to fold up a Jayco camper trailer bed canvas like an envelope:

  1. Fold the corners of the canvas into the middle of the bed

  1. Fold the long edge of the canvas back into the middle

  1. Push the bed in slowly, neatening it up as you go

I’m not even sure where these pics came from (they’ve been shared by so many people)…

…but whoever took these photos is a legend!

When you’re packing down, don’t forget…

16. Remove rings and use the back of your hands when pushing in the canvas

Anyone who’s wound down the roof of a Jayco camper trailer knows that you need to stop a few times to go around pushing in the canvas.

But something that some people have learned the hard way?

Fingers can poke holes in the fly screens, and diamond rings can get caught

[especially as the fly screens get older]

Jayco Camper Tip - Use Back of Hand To Push In Canvas

So a big tip is remove jewellery and use the back of your hand to push in the canvas so that you don’t accidentally stick your fingers through the flyscreens.

17. Don’t worry about the ‘clunk’ noise when you’re about half way through winding up the roof

I was skeptical when I was told this at handover:

“Don’t worry about it, it’s normal, it’s always done it”

I wasn’t convinced because there was no REASON given…

…but it’s a question that gets asked all the time.

It turns out that it is normal for a wind up camper system, which winds a cable around a winch drum:

Winding the Main Cable Back Onto Jayco Wind Up Camper Winch Drum

The cable slips on itself as the first layer is complete and it’s starting a new layer

(TIP: I use it as my cue to go around and check that the telescopic arms have lifted)

18. Adjust your roof clips so that they don’t come loose while you’re driving

You can adjust how loose or tight the roof clips are by twisting them

(they have a nut and bolt built into them)

Twist The Roof Clip On Jayco Camper Trailer To Tighten or Loosen

So any time you go to clip down your roof and it feels a little loose, it’s worth adjusting them so they’re snug.

I’m sure you don’t come loose often, but if they do, once is enough!

19. Don’t plan on your power points working if you’re not connected to mains power (unless you have an inverter or generator)

A simple way of looking at things is that you’ve got 2 separate electrical circuits in your camper:

  • Your battery powers a 12V system
  • Your power points run off a separate 240V circuit

So if you’re not plugged into mains power, your 240V power points won’t be live

(this includes USB chargers if they’re part of a 240V power point)

ReadPop Up Power Point for Jayco Swan (Installation and Review)

So if you’re free camping plan on cooking on gas…and buy 12V appliances where you can.

If you insist on using 240V appliances, you could:

  • Get an inverter (but you’ll more than likely chew through your battery really quickly), or
  • Run a generator (but be prepared to lose a few friends)

20. Make sure you have the right 15A gear to plug your camper into 10A mains power

The electrical system in your Jayco camper trailer is rated to draw up to 15 amps of current at once…

…while your home runs on a 10A power supply.

So to start with, you need a heavy duty extension cord that’s rated to 15 amps

(which won’t fit into a standard power point).

Then you have 2 options:

  1. Get a qualified electrician to install a 15A power point to plug into, or
  2. Purchase an approved 15A to 10A adaptor (which is handy for travel anyway)

Ampfibian 15A 10A Adaptor Most Popular Caravan Safety Accessory

And no:

Changing the head of the power lead to a 10A one or grinding the earth plug down to size are not options.

The most popular and best option is an ampfibian adaptor. You can get them at Bunnings, but we bought ours a bit cheaper here off eBay.

21. If you’re using an awning make sure you have a way to even out the tension on the other side

When you put up an awning (or annex) it can pull the roof sideways.

This can:

  • Put a bending force on the lifting arms
  • Stop the door frame from being in alignment

One option is to replace the lifting arm bolts with eye bolts to create a spot to connect guy ropes…

…but another option is a kitchen awning privacy sunscreen:

[get them here from eBay… perfect for keeping the sun off the fridge in summer]

22. Protect the 12V plug that’s near the sink from water with some plastic tubing and a chopping board

<insert your favourite joke here about this amazing Jayco camper trailer design feature>

Protecting the 12V socket from water is important for obvious reasons.

A culprit seems to be when you connect to mains and first turn on the tap:

Water can come blasting out!

Some tips that a few people have done to help this include:

  • Attaching some 8mm tubing (Bunnings) to increase the length of the tap
  • Placing a chopping board behind the tap and in front of the 12V plug

23. Know how water affects your weights

Here’s a couple of important numbers to know:

300 kg is the standard load carrying limit for a Jayco camper trailer


You’re carrying 82 kg of water when you fill the standard 82 L capacity tank

So it’s worth keeping those numbers in mind when you’re wondering whether you should travel with your water tanks full…

…especially when you consider that the 300 kg limit includes your awning, aircon, solar, etc

[there’s no straight answer about how water will affect your tow ball weight because it’ll differ depending on where tanks are relative to your axles]

Summary: Tips for Jayco camper trailer owners

I’m sure this is just scratching the surface of tips for Jayco camper trailer owners

…but these are the ones that jumped out at me as important to know

(and I only learned most of them AFTER we started using our Jayco Swan)
