I have one of these in my backyard waiting for a turnaround.
The walls look very much like the pictures,but they are just raw
fiberglass.
I had to look twice to decide that the ebay trailer actually has carpet.
close examination reveals what looks like the carpet is fastened to panels which are then attached to the wall.... could be wrong, It looks like a Jim Henson design interior
We plan to use ozite where needed.
