2306BHS (Leak, condesation, other "Warranty") Thoughts?

We have owned our 2019 2306BHS now for just over a year. I wish I could tell you it has been problem free, but it hasn't been. We have had the HVAC replaced, the Furnace Repaired, The water heater board replaced twice, The tongue jack fixed twice, a trim issue where the slide wast catching on it repaired, and a few other smaller things.

Christmas, we went camping, and when we got to the site, I noticed that water was dripping from the rear near where the bunks are. (Not an area where there is much plumbing, but that's where the city water comes in.) It seemed like quite a bit of water. I sliced a bit in the belly fabric to see if water would come out, and it did about 2-3 cups worth. I felt, and the insulation was super damp. Ouch! I modified the back with a service hatch so I can see the pluming side of where the city water comes in, and it was dry. It wasn't coming from there. There was no water at all inside the camper, just underneath in the insulation and belly cloth.

The whole time we were there, I did not notice any more dipping or additional water.

When we got back, my wife called Winnebago, and because we had had more than our fair share of problems, they agreed to pay for the repair if the leak could be found, and it would have been something that would have been covered under warranty.

I took the camper to the dealer, knowing that I would have to pay out of pocket for a diagnosis. I feel they have been fair to us with the cost of $175.00; they spent a lot of time tracking down things.

Good News:
Plumbing is fine. Pressure tested no leaks.
No water leaks in usual places, (Sink, shower, toeliett, etc.)

Possible Not Great News:

There is a slight leak (If you call it that) in the freshwater pump check valve that has allowed water to get bypass and get into the fresh water tank and fill it up. Cycling the pump can stop the leak, but switching back and forth from city to freshwater tank water, the valve doesn't alway seat firmly.

There was a slight leak at the freshwater fill tube that a 1/4 turn on the hose clamp fixed.

But...the freshwater tank sits below where the water was found so even if there as a leak, it cant explain the water.

The plastic trim that covers the wheel well's caulking had seperated. It is possible that water was making it's way past that and getting into the belly. It was reinstalled and recaulked.

So Current Theories:

Condensation of some kind on that side of the trailer.
Wheel well sealant failure.
The water from the fresh water tank still found some way to make it to a place that doesn't seem logical.

Main Issue: We don't have a reliable diagnosis or repair stratigey. The dealer can't come up with a warranty repair issue from the symtoms.

What's next?

The dealer has two suggestions.

1. Call Winnebago and see what they tell me. Winnebago is saying to them they have not found a repairable warranty problem yet.

2.They suggest to just replace the insulation with foam board and call it good, hoping that it was condensation or the wheel well sealant.

I called Winnebago back. So part of my issue is that the dealer and Winnebago have parted ways. The dealer is allowed to service what they sold, but they are no longer a Winnebago dealer. It feels like part of my issue is a "divorce" issue. Winnebago said that if I take it to another dealer and pay them for a diagnosis, and it is a problem that the original warranty would fix, they would cover it.

The problem is the dealer is over an hour and a half away, and a call to them did not give me any warm feelings. They were friendly, but I would have to take it down there leave it for a week or two, and I could have a few hundred dollars into their diagnostics. It might even be a problem they can't fix under warranty.

So.....i did an unspeakable thing. I decided to cut into the underbelly!

I'm glad I did. I first just sliced further into the side that had the water leaking. I could see some water staining. The good thing is its just a little staining. Wood is super stable, hard as a rock, and no visible mold growth. Glad they use plywood and not OSB for the subfloor. I then sliced into every part of that did not have the coroplast covering. Ouch, wet insulation! Most of the wetness was at the lowest point is in the belly fabric. Only the sides had any hint of water staining. And as you moved towards the center of the camper, there was no water staining.

Problem is whats under the belly fabric where the coroplast sits? I took off the stabilizer jacks in the back and got into the coroplast a little, just enough to look. Dry as a bone, but above the tanks is the belly fabric I can't get to and insulation. I can stick my hand over the frame in there (Belly fabric & insulation) a little, and the insulation feels dry. There are a few penetrations from inside I can get to, and when I feel there, it feels dry.

To do a proper job of checking, I would need to drop the axels and cut out the coroplast some. I don't have what I need to do that. Guess that's where you pay the few hundred dollars to have it checked out.

Questions:

Since everything feels dry, there is no water staining as you go inward, should I let it go and feel ok?

Do you feel the theory of water getting in because of the wheel well trim and wheel wells not being sealed well was a good theory, and that was the most logical problem?

Last, what should be my next steps?

Here is what I am thinking.

1. Use 1 1/2" XPS Foam Board to fill in the voids where the insulation was. It doesn't wick water and should provide protection for the plywood above incase of further moisture issues. I will cut it to fit and glue it to the underside. I will then seal the edges with silicon.

2. I will temporarily tape the fabric back to the foamboard and eventually replace that with coroplast. I would do it now, but I can't find any black coroplast in my area, and white doesn't seem as attractive to me as black.

3. I will further look for areas to seal or might need sealing. The dealer resealed the trim and said they put sealant where it seemed like they didn't use enough glue.

Do you see any major pitfalls here?
Anything you would do differently?

I completed the job. It was certainly and ordeal. It didn't quite go as planned. I went with 1 1/2" XPS rigid foam board. In most places, it seemed to work well; on others, there were areas where there wasn't quite a 1 1/2" clearance. I did the best I could. I decided not to use the glue in case it needed to come out someday. There were a lot of extra "mistake" holes underneath there. Places they drilled and or put in a screw that they didn't use or seal up at the factory and didn't use. Overall I saw no water damage to anything. Just some water staining on the belly fabric and a little on a few spots of plywood. I also reinspected all my sealant. It all looks fine to me. The dealer said it was fine when they looked, but I did it again. I probably have been more upset about this than I should be, but I want to use my camper for many happy years. I think it boils down to the fact that I can't tell you for sure my issue is fixed. No plumbing issue, No roof issue. Dealer thought it might be the wheel well trim and a poor glue job on the wheel well. I'll go with that. I'm going to look at the wheel well with fresh eyes later to see if there are any areas I could seal that would make me feel better.

***YOUR WATER PUMP needs to be replaced because of that faulty check-valve. WARRANTY REPAIR **** If I understood correctly it is causing water to be diverted into the fresh water tank from city water...


Could the water be telemarking its way down from a window or joint in the external walls or roof. Water travels long distances and can follow wire, framing, pipes etc etc.


Best of luck to ya, glad to hear that bago is not being too much of pain in the back!!

We had a problem with water leak under trailer the first time out with our 2020 30rlss. I videoed the water dripping to show the dealer. I left it with them for about 2 weeks and they dropped they belly they had a terrible time finding the leak but as a last resort ran water in the shower and that is were they found a cracked shower drain. I am very happy that my dealer stuck with it and found the leak.
