The trailer has rotted wood for about the first 18" on the whole length of the trailer (23'). It has 2 entry doors that the weather seal is shot on and I believe that's where the water came in at. The previous owner told us he went threw a huge storm and one door wasn't shut all the way and it happened but, he fixed a portion of the easy stuff (He's an 80 yr old man). I was amazed at the condition of the trailer for the price and got blind and dumb and didn't inspect it more before bringing it home. Once I got home, I saw the extent of the damage. It's all on the one side of the trailer where both entry doors are. There is no damage on the walls, ceiling, or where the the water tank, water heater, or bathroom are. That's why I truely believe it's from the bad weather seals. The floor is definitely shot though for the first 18" or so. It's not really the entire length but, it's about 80% of the length.
You could take it and get an estamate, then when you do it your self, you can think of all the money your saving. I was surprised at how these things are built when I fixed that other one. I would check the bottom of the trailer also. The fabric on the bottom is to keep moisture out. If it is ripped or torn, the tires will soak the floor.
If you know how to do this kind of work its not bad, just make sure to look where your screw'n things into. You have tanks and wiring under the floor.
They probably sheeted the floor of the trailer first and then built the walls on top. So that might be the tricky part for you.
