Roof panel replacement

[Ryanr419]

Hi all. I'm new here. I have a 2001 r-vision trail lite b19 that got given to me. The floor was spongey, and a roof panel needs replaced in the back part of the camper. I replaced the entire floor, (nightmare project), the problem I have now is I'm afraid to rip down the ceiling without knowing what I'm getting into. Like how far apart the studs are, etc. Has anyone ever ripped into one of these? I've searched and haven't yet found anything online about the trail lite ceilings. Thanks all!!

When you say a "roof panel" needs to be replaced, I'm assuming you mean on the interior? If so, that should be easier than replacing the floor, which you've already done. The bigger question is the roof itself. Have you found and fixed the leak that let the water in? Have you checked the roof decking itself? If not, I would bet you have some rotten spots there also. It's all doable, it just takes a lot of time. I replaced the roof, rebuilt most of the front end, and 3 sheets of roof decking on my Jayco last summer. Had about 120 hours in it when all said and done. In my case, the roof "trusses" were bascally 2x2's. You will also have some nasty insulation to replace. Good luck, but it sounds like you're up to the task.

Just a guess it will look something like this .

Yes your correct about the interior panels. I didn't see any damage from the outside. I assumed the the caulking needed redone (which I did on the entire roof). My bantam trail lite is an aluminum frame. There are no wooden trusses and the roof is basically two quarter inch pieces of plywood sandwiched between 1 and a half inch foam board

Your roof is laminated foam board, just like the sidewalls. Framing layout depends on manufacturer and would need the engineered drawing to know exactly where they are.

Why does the roof need replaced? Is the 1/4”ply rotted on top or bottom? Has it separated? Depending on the condition will determine steps needed to fix.

Normally a laminated roof will not mold or rot like a truss style, that’s if you catch it soon enough. Then only glue and pressure is all that’s needed to repair.

Its soggy the whole way through. There was a leak in the bathroom that I believe was from the vent lid. I have everything resealed now. There has been no evidence of leaks in the trailer since I resealed everything. The campers not worth much, and I have no plans on selling it. I just want functionality. I was think of just tearing out the bad section and screwing new plywood to the aluminum cross pieces of they are not to far apart

Sounds like the 1/4” plywood has separated layers.

Cut out and remove the old, and glue a new sheet to the foam board, and framing. If you have cabinets involved it makes the process more difficult.
