I have 3 spots where the side of the camper is no longer tucked under the trim. It's so short I don't think I can get the trim to cover the siding. What's the best way to seal these areas?

I found some Loctite All Purpose 2 in 1 Seal & Bond. Will that stuff work?

I agree with previous posts that this type of issue is likely indicating a larger issue inside causing the material to expand and separate. Here is my advice:
- Do NOT use DAP anywhere on your RV - its a recipe for disaster
- The only thing worse than DAP is silicone
- Do find the original leak and fix it (most likely above) as other have posted'
- Do dry the interior completely - removing panels if necessary

Patch with Proflex or a similar RV exterior caulking. I used Wurth Bond and Seal and it is amazing - hard to get but amazing. As other have said above Eternabond is a great product, in my opinion though it is very unsightly in visible areas like you have here.

If the area flexes too much and break the caulking bead you have no choice but to open the area and fix it.

BTW: the point above about the whole area blowing away when driving is nonsense (in my opinion anyway)

I would not drive that too far or fast, you may end up with a convertible. That under side should not be on the cab roof, indication severe structure damage. A complete rebuild is in the future. While working on the inside you may end up on the hood if you are as heavy as me!!!!!!!! Good luck.

That much separation (especially on both sides) likely means major water damage. Don't open anything up unless you are ready to completely rebuild the cabover.

To patch for now and address damage later, I also recommend Eternabond. Don't remove trim or dismantle anything. Just put the eternabond over the top and then get the roof leak figured out. You need to stop all water entry from the roof.

Good luck.

Sealing the seams that you show in your pictures will only make water collect in cab-over. Leak is probably some place in the roof area. 3 most common are clearance lights, roof seams and front window.

As some of you may know, I've dealt with a cabover leak for some time. If I had it to do all over again I'd get directly to Eternabond tape. I've enjoyed Winnie through 23 states and over 20,000 miles and will continue to enjoy. Just my 2 cents.

all the above its leaking up high runing down ,and the woods already shot,gotta come apart.

More than likely there is already a lot of rotten wood and dangerous mold. Your choices are very limited. Junk it, or take everything apart, eliminate all dangerous mold and put it back together right. Patches are not going to cut it very long.

Why is it pulling apart?Sealing it may stop some leakage,but the underlying problem is what you need to fix first.

The side sticks out so much I think that most of the std stuff isn't going to work ... I would go with Eternabond tape.

It's likely you have significant water damage in the cab over area - that might require a rebuild for a proper fix - there are lots of threads on that subject which you can access using the forum search feature.

I'd second all these points. that kind of damage Eternabond is a quick fix for a season or few trips, but it's going to require some more work to do it right.
Kinda like what I had to do for RoadAbode's Rear

I covered it up with Eternabond until I could get to it and fix it proper. Good Luck!
