Thanks for posting the pictures of yours.
I opened up my basement panels expecting to find a mess but was pleasantly surprised. Everything was for the most part orderly, no hoses kinked, and only a small amount of sawdust and two loose 2x2 blocks of wood. I guess what's behind the walls really doesn't bother me because with all that these homes on wheels come with, there's bound to be a mess of wires hidden somewhere. If you look behind the entertainment center of my sticks and bricks home you'll find an even bigger mess of wires.
