yes, thanks I found that out they could get sheets of almost any length. also, the frames to secure to aren't always consistent due to the black and grey tank locations. I learned a good lesson when I jacked it up...I raised one corner, all the screws were out, and when I got the body up it shifted to one side about an inch !!! I let it down, it came back to where it should be, then i put a thin board along the back and under the wall plate, but in the middle. I went up slowly and lifted the whole back evenly. if this were inside, I may have considered raising the whole body off the frame about a foot or so, then I could have removed the floor. propane lines would have to be removed from below. luckily on this trailer everything but the propane lines are above the floor.
