RV damage after accident

A big roll of Gorilla tape will get you home.

Just trying to get home? Screws to reattach the wood as best as possible. Might have to use some extra pieces of wood to help hold it all together. Heavy duty stapler to stick the aluminum back on. Then duck tape all the seams to prevent wind/blowing air to get under edges and raise them up. Then drive slowly on back roads.

Make, model, year, and what type of RV? Trailer, 5er, MH, Pop-up? Where's the damage, front, rear, drivers side, passenger side. Not enough info.

As with any damaged vehicle, the only thing you can do is start disassembling the damaged area until you reach undamaged area. Replace the damage with new or good used and hope it all goes back together again.

If your camper is aluminum skinned with wood framed walls, you'll just have to rebuild the damage, much like you'd rebuild a wall in a house. But, without more details, it's hard to give any suggestions.

Can you link to photos? You're description does not really tell us much, how extensive, where on the trailer, etc.
