Re: O/T Camper repair
If you have the available time, tear into it! They are not really that hard to repair. You will find along the edge a channel with a rubber strip in the middle of it. This channel separates the sides from the roof. Pull up that rubber strip and you will have a row of screws. Remove the screws, pull off the channel (easy to say as usually there is gobs of caulking holding it on). From there you will be able to remove the aluminum skin on the roof. The aluminum panels will have channels that slide together to make a waterproof seam (I would just remove it as one piece if there is no damage). Under this skin you will find a wooden frame. Repair from there as needed and frame in your roof vent. The roof vent is where the air conditioning will go and also do not forget to run the wires for the AC at this time. Any RV shop will have everything from the caulking to aluminum replacement skins to purchase.
It is more time consuming than difficult to do.
In a storm, I had a nearby tree split in half and fall through the roof of mine. The insurance company wanted to scrap it. So, they paid me off, I bought it back, repaired it, and had money in my pocket to boot.
Hope this helps, good luck.
