I just bought a 98 Trail-Lite by R-Vision and really don't know much about them. Since I don't see any around, I wonder if there is something wrong with them? It has an aluminum frame and fiberglass shell with foam insulation glued to the walls. Is this a good construction method? Compared to an aluminum shell that I see on so many campers? It's supposed to be very light and the owner was very pleased with the non-aluminum shell since his was the only camper that wasn't dented during a harsh hail storm. If you have any thoughts on this brand or the way they are built? Thanks!
