I am selling a peerless wood chip/trash/shaving semi trailer which i believe is from the 1980s. IThe tires hold air. It has aluminum walls with steel supports. The plywood floor needs replaced but the metal floor supports are all good. It hasn't been used in a long time but could be quite usable with a new floor. Current PTI registration. I know a lot of these type of trailers are being used in the Camp Fire clean up.
