regular vs light weight

I guess I've always equated Lite with cheap entry level junk cuz that's been my experience. There's nothing wrong with lighter if there's some build quality there. I used to be so worried about weight and overloading my trucks so I bought the lightest RVs and they had thin floors, roofs, minimal insulation and even no vapor barriers. They were flimsy and flexible, fell apart and couldn't be heated if the wind was blowing cuz air went right thru them. Just check the construction carefully and that goes for anything you buy. Craig
