Is the frame work on the Hi-Lo's wood or metal?? Especially the newer ones.
Mine is 2006. Is it a metal skeleton and then covered with board?? I would hope as far as to what the cables are attached to and so forth as wood would seem to have too much flex. Thanks.

According to the HI-LO brochure it is a metal frame cover on the inside with plastic covered thin wood paneling. Styrofoam in between and fiber glass covered wood paneling on the out side. There may also be other parts that are wood. HI-LO TowLites in the 90tys had a wood frame.

Look at the cutaway picture in the 2006 brochure, it gives you a basic drawing of the framework.
