Are pop up campers waterproof ?

Pop up camper are great for boondocking and they give lots other advantages. Easy to tow and light weight pop up campers are less costly and are great for beginners. They however do not pack in many amenities but just the appliance/items you may need.

Folding pop up or tent trailers are awesome but are they great during bad weather conditions like rain? Do they leak water when raining? Lets find out if they are waterproof or not.

New models of pop up campers are waterproof but with time they may loose waterproofing. Used old pop up camper canvas may not remain as good as it was when new. Thus waterproofing may be needed from time to time.

The pop up camper canvas in newer models is not pure canvas but its mostly combination of canvas cotton and vinyl. Vinyl material gives good waterproofing to the pop up camper.

Different materials on the pop up campers

Pop up campers have fabrics that could be vinyl or canvas cotton or it could be both vinyl plus canvas. Most new models come with vinyl that is very much waterproof. Canvas made up of cotton is not highly waterproof and thus coating of waterproof is added by manufacturers.

Old pop up campers came with only canvas and if you own a newer model then it will have very good waterproofing.

Having a combination of both vinyl and canvas also works great as they both have their own advantages and disadvantages. Thus if you bought a used camper then you are likely to have both of this as fabric for your camper.

Vinyl fabric has better ability to repel water and avoid soaking. Thus it keeps the water away from entering inside. Canvas has less capability in doing this.

Thus if you are going to camp in a rainy weather then keep this point in mind. Vinyl will shed the water pretty well and thus provide better camping conditions in rains. Canvas fabric however can be waterproofed to keep the water out.

Vinyl material can result in condensation which is lesser in case of cotton canvas. Thus having a combination of both works great.

A canvas on the inside and a vinyl on the outside can work great.

This will prevent the water leak as well as condensation on the interior. Condensation may look like water leaking and many people mistake condensation with water leaking. It will be like water leaking inside but if you observe closely you can figure it out.

Condensation can result in mold and mildew which again can cause musty smells and odors. Hence you need to be careful of that too.

Reasons behind pop up camper leaking

Its not that all pop up campers leak. If you own a used pop up camper and its leaking then there could be issues with how it was handled. There are several reason why it could leak.

An old canvas on the pop up camper may damage with time specially when it has to withstand UV rays, and other harsh weather conditions. So timely maintenance is all it needs.

A newer model will have better waterproofing and may not need any such coating or treating. So be sure that you don’t do necessary things with its canvas fabric.

Its design too can result in leakage, UV rays can make caulking detoriate and result in leakage. So the idea is to make sure caulking is restored and getting any holes sealed. Bunk end leaking is another issue specially if its coming down heavily.

Some people also use tarp over bunk ends and that may help in both keeping the heat out as well as providing some protection from rain. Its bad when you get you camper bed wet, this may happen due to both condensation as well as direct leaking.

You have to figure out why its happening and then address the issue. Condensation is more common and can be addressed by using different techniques. You need to have good ventilation or have heater or ac that can help get rid of it.

Having an air conditioner or vent installed on top can also result in opening that will bring in water drops. So, you need to make sure any screw be tighten properly.

Resealing the roof

When you install an ac or a vent on the pop up camper its important that you reseal any holes or openings else it may start leaking from there. The roof of the pop up camper can loose its strength after withstanding the sun, rain and UV. And caulking may be needed.

People use silicon as the roof sealant but it may not allow paint on it. So that’s one point to keep in mind. For sealing the seams on the pop up one can use ethernabond tape. It can work great in sealing the seams. Using silicon caulk however may not be good idea. It can shrink and pull away resulting in retaining dirt.

You also get paints that act as sealant as well. One such product is kool seal. Using a good primer along with paint can also work well. But, it depends on the type of roof material it is. You can use a paint roller for putting it on yourself. Roof resealing is needed to make sure rain doesn’t come in. And trying these various things should work.

  • It may tear
  • normal wear and tear, as its exposed to UV rays and sunlight
  • holes to external elements

One can sew the holes to make sure its not leaking. For this, make sure you use different piece to sew it together else the waterproofing may go away. Getting the holes sewed as early as possible is necessary else it may become a bigger problem.
