I've noticed large differences in quality and weight of many construction items. LT's generally have thinner, lighter cabinetry. Walk into most LT's. Pull on a cabinet or drawer slide and note the flexing of the surrounding cabinet. Often you'll see considerable flexing. Open and close the bedroom or bathroom door and note the lighter weight construction in the door frame and walls. I find the construction in heavier trailers to be far more solidly built.
Outside look at the hatches. LT's will often have much thinner lighter hatch panels.
When changing stereo speakers inside on my Winnebago I saw the ceiling is 1/2" thick plywood. On a friends Heartland XLT the ceiling was 1/8" thin paneling. The Winnebago is still considered an LT but not advertised as 1/2 ton towable.
Inside and out I noticed considerable differences between the 1/2 ton labeled LT's and the somewhat heavier trailers. Move up to the higher end trailers and the differences are even greater.
