I see trailers with no roof or half roofs like that all the time. May be a Kansas thing. It gets so hot here I find it difficult to keep mine (enclosed) cool enough for the horses.
Is it a half roof or is that the part that was wrecked KT? Reskining it should be a fairly easy fix for a handy fellow.
