waterproofing slide floor

Good point Jbarca. Mine wicked it's way in from the strip that attaches the floor to sidewall. The vinyl strip had shrunk that covers the screws and allowed water to be wicked in. Compounding the problem Forest River left a quarter inch gap in the siding and the rain gutter right above the area on the side of the trailer.

i am out of town getting some ongoing health care but will definitely post some photos when i get back in 2 days.

What is a slide topper? Not familiar with that but sounds like something I need.

A slide topper is an awning that covers the slide and goes in and out automaticlly when you deploy or bring in the slide. I have had them on my trailers for years and would not have one without them.

Be careful if you order one online that you are getting the hardware and not just the fabric. Here is an example of the complete package.

No rush on our end, post when you can.

To add to Barney's great post

When adding a slide topper, you need to "make sure" the topper fabric length is "longer" then the slide. Even if a dealr is supplying and installing it. Some brands, (Dometic for example) go by a generic topper size. That generic size is not the length of the fabric, but more a nominal frame length to fit onto a slide room of a certain range of sizes. Regardless of the brand, Carefree, Dometic or Lippert, make sure the actual fabric is longer then the actual roof of the slide. It should be longer by 1 to 2 inches or more longer if possible, on each end then the slide roof. If your camper already has an topper gutter rail with the cord slot, then make sure the fabric is not longer then the cord slot too.

Some brand new campers on a dealers lot have the topper shorter then the slide roof. That is "not" what you want.

When the time comes, and you get close to ordering a topper, check back with us on which to order and how to mount them. Yes, many have been mounted wrong, with very little pitch or negative pitch even, to them making them not as effective on shedding water off the slide roof.

I do agree, after what I went through on my slide, I will never own another slide camper without a topper.

That said, we still need to see your pics as the leak path can be from many areas. The topper will not correct for a bad design on the slide floor setup.

Hope this helps.

unfortunately the water damage occurred while I was having emergency brain surgery in Florida in the middle of a pandemic, followed by 2 months of f radiation and chemo. While I was stuck in Florida the RV was home in Texas with the slide extended when a big storm apparently hit. The good news is the surgery and subsequent radiation and chemo turned out very well. But by the time I got home the floor was rotted out. I was thinking that if I had waterproofed the floor the damage wouldn't have been as bad.

I appreciate your comments about not sealing the floor. That makes sense.

I will tell you to be thankful for what you have. When you are a 20 year old you feel invincible. When you are 65 and one emergency surgery and a few hours away from death, you get a new appreciation for the things that are important.

Wow, sounds like the least of your trouble was the camper! Wishing you a speedy and total recovery. Post here when you can , and these guys qill help you figure it out. I will also agree, when you get older stuff dosen't work or heal the same. Life is too short to sweat the small stuff, have fun with what you can while you can.

Ill also agree that it sounds like a seal or something failed or wasn't in corectly. But who knows.

100% agree here. I don't want to speak for John, but what he discovered was that water runs down the exterior side of the slide out, and via surface tension runs under the slide bottom before dripping off. This allows water to wick in and rot the floor. John discovered and repaired this, and I followed his tutorial when repairing my rotten slide floor as the damage had been caused by the same situation.

The fix was to install a drip edge on the bottom of the slideout sides so that water dripped straight off without following under the bottom, so it has no chance of wicking in.

The slide topper awning is wider than the actual slide, only by a few inches, so that water drips directly off the awning and not down the side of the slide.

This may or may not have been your particular issue, so your fix may not be the same, but if the floor rotted once it will rot again unless you find the root cause. If not, sell it now while it's newly fixed!

i suspect that is exactly what happened. and exactly what the repair man told me to do if it happens again (sell it)??if you can share a bit more detail about what to use for a drip edge and how to attach please do so. i love this forum everybody is so kind and helpful.

Im curious also as to what the drip edge set up looks like. I have a rear slide bed, no way to get a cover for it. When i first bought it, i qent on a long trip and noticed it was wet inside the camper. Dumb me checked everywhere for leaks. Then it dawned on me that the condinsation on the top of the slide ran off in the camper and made it wet. So, hours of looking for leaks for no reason. Now i dry it off before taking it in.

Hi,

I have all the pics and background on both of my slide issues. The one Burbman is talking about above, and a new one that happened a few years ago with water flowing in a sliding end wall window.

This post here on RV.net is the first one with slide floor rot in 2010 that Burbman followed and fixed his. There are pics of the problem, and later in the thread, how I repaired it and created a drip edge.
https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/23443150/srt/pa/pging/1/page/1

Since that time in 2010, I have followed the RV industries changes in slide manufacturing. And the trials and tribulations of how several of the next generation slide design changes, fixed one problem and created another. Which in turn, creating follow on changes again... Now a days, some brands have changed the way the slide floor is made and sealed at the floor level. Other brands still keep creating the same issues from 10 year ago. Every time I go to an RV show, I look at all the brands and how they build the campers and the slides. I'm under the camper looking up, and the wife in side looking at the inside...

This is where pics of your slide will help show what "vintage" your slide is made to. And how it may be able to addressed if it has any of the older or next generation issues. When you get time to post them, we can see and possibly help on what the new fixes are as they are made different then mine.

My other issue more recently was with water coming in the slide open window in the end wall of side room. I did not post this yet on the web about the problem, nor the correction so I can't link it, yet anyway. If your slide room does not have a window on the ends of the slide that opens, then it won't be an issue. If yours does have a window that opens, I can load up the pics and explain once we see what yours looks like.

Hope this helps

Hi folks after some on-going health issues (all resolved, all well) I took a new approach to solving my leak issues. I found a young guy who works in my RV park who does minor repairs on the side, and he has caulked up many questionable places on my roof. Someone said you could help more if I posted a photo of my slide. The right corner of the slide is where it leaked before the floor was replaced. I call reach under the slide and feel the new floor, which is now wrapped in some sort of waterproofing material, but it still disturbing that I can reach it so easily, which means moisture can too.

As usual, your suggestions are appreciated. I haven't posted a photo before, so wish me luck. Oh, and there is a window in the side of the slide, but it doesn't open.
