Hi Rocky! I love my Caravel
, it's a great little trailer - the perfect size and very roomy layout.
Poke around inside and look under all the cupboards and try to see if there are any more rotten spots in the floor along the edges where the walls meet the floor. Since you already know of a couple you'll know what they look like. A lot of trailers have rotten floors, and there are a lot of threads on the forum dealing with how to fix them. It depends on how far the rot has gone.
Check the axel. Read the article on www.inlandrv.com
to learn about how to tell if the axel is still good.
Too bad about the door blowing open, but it happens. Dents and tears on the outside skin are about the worst thing in my opinion. Appliances like the fridge and AC can be pretty expensive to fix too. But everything can be fixed, you could stip the shell off the frame and rebuild it from the ground up if you wanted to. It really depends on how much work you want to do. Like I said, it's a great little trailer, and the prices are going up up up so if it's a good deal, buy it and fix it up, enjoy it, and probably make a profit someday when you sell.
