Constant water problems - 24F

My FW 24F is 27 months old from date of manufacture - I have had it for 22 months. Over those 22 months water penetration in the coach has been an issue - stove vent was not sealed on the outside, slide trim not sealed, cab over window not sealed. One thing after another. My latest adventure was getting the coach ready for a trip after a rainstorm. I found both sides of the cab over wet on the inside, I mean wet, and water still dripping. I was able to trace the leak to the corner molding that goes from the roof the the bottom of the coach and it had no sealant on it. Water was getting under the molding, has soaked the wall plywood and now water has a way into the coach. Now I have a slight moldy smell inside from all of the water. And, the trim inset started to come off the coach. I was ready to get a match.

I pulled the trim insert out and was shocked at what I saw. Almost all of the screws on the underside of the cab over were rusted, some with the heads broken off. There were a mix of stainless steel, inside panel and countersunk screws installed - whatever was on the shop floor.

I spent the day yesterday removing each screw, filling the hole with silicone and replacing with stainless steel pan head screws on each side of the coach. Then installed new insert trim.

Next I went around the complete coach and sealed every corner and penetration on the coach with clear Geocel Proflex sealant. Not easy stuff to work with, looks a bit messy (operator induced) but the coach is sealed.

Water has been the bane of my coach over the past 2 years.

So sorry for this experience. I just did my first spring inspection and sealing adventure this last weekend. I spent about an hour and a half and addressed 4 different seams one of which had been leaking for a while over the winter. I do this at least 4 times a year and nearly always have to address something. Itís not much fun but Iíve come to know my coach very well by doing it. EVERY seam needs to be clearly and obviously water tight with a good fillet of appropriate sealant. Keep at it and you can get ahead of it.

I'm feeling the same pain

My RV has the same problem. Not on the side you show in the picture, but in the opposite side.
Took it to Camping World and they told me I left the window open

I guess I need to take the trim out an re-seal it.
Hope you fixed the problem.
Did you have to replace any plywood? I'm afraid that the mold might be a hazard!

This ius the sort of thing, that makes folks wonder why they do this...

Sorry to hear that you're having such problems. I hope that you can get it all sorted-out, and then dried-out! Good luck!

That is a crying shame......

These manufacturers need to step up to the plate and make the standard warranty 2 years. It can easily take that long to shake out and address all of the issues that are part of well-documented poor manufacturing practices coupled with little to no quality control.


At the very least, they should stand behind these coaches for 2 years for water penetration issues. Water can do more long term damage than anything else.

Jimbo12, all I can add is to say, you are not alone.

mine was/is the same way. Hopefully you got her before too much damage was done. teh up side is that there really is very little wood in the walls. On mine the only substantial wood walls are teh short wings just behind teh cab doors...that's where I first discovered my roof/corner insert trim leak. I had some bad rot there.

I your want just to ease your mind, the upholstered panels on the inside are easy to remove for a look-see.... just pry off the button snap covers and remove a few screws.

Judge, I donít know if itís the same for all manufacturers but Thor only warranted my Freedom Elite for 3 months on water penetration. On the one hand it sounds like they have little confidence in their product but I think the reality is that sealing is an ongoing maintenance item with a frequency need of 3 - 6 months. RVs are made of lightweight materials and they flex and move a lot in use. I rarely go even 6 months without having to address sealing issues.

Iím sure Iím in a negligibly small minority on this but Iím just as glad my warranty is expired. Warranty service is slow and poor in many cases but you feel compelled to use it. It might cost a bit more but going to a good independent shop that values your business will get your repairs done right and put you back on he road I days instead of weeks.

The sad thing is we seem to expect or accept poor quality from the manufacturer. Can you imagine if my new Jeep or Ford F-150 was built to these quality levels? It is a sad situation where quality control is almost non-existent, the dealer warranty service is slow or poor, and we consumers simply accept the situation. There is no other consumer product that I know of that is built to such low quality levels.

Buying one that is 2 years old may be a good deal because it takes 2 years to find and repair all the initial defects.

Just my opinion, of course. Jim

Our Quantum is the same way. Last month I found all the plywood in our entry step was water soaked and delaminated. I tore it all out and replaced the cheap wood with marine grade ply and caulked the crap out of things. Now just today I discovered our wing walls are rotten as well. We're at 18 months on our 2018 so not sure what we're going to do about the walls.
