On the sixtys models a bit of floor rot at the door seems to be a normal problem. I belive it has to do wothe the fact that the door is flramless where it joins the shell, and as soon as the weatherstripping gets bad you have a leak. If the soft spot is 9X9 or so and just a soft spot, not a hole, it can be fixed with rot doc or git rot and the floor can be filled. I did this on a 65 Safari I had. You cannot tell the floor was fixed except for the not quite as yellow tile.
The wheel well wear and repairs are more of a concent to me, but that would oly be because I do not know how the damage might have happened. Was it a bad Axle? Loss os a tire? Was the seller able to shed any light on the damage and the subequent repair. Will the trailer need new axles?
Door hinges wera, I think they can be bought new. I would look at that as a maintence need, just like door and window gaskets, and tires/brakes.
Just my $.02 worth
