Jane,
There are plenty of differences in how various manufacturers construct their "Lite" series RV's. Some skimp on: Frame strength and metal thicknesses, floor construction/strength, wall and stud size and thickness, roof thickness and truss strength and/or number of trusses construction, and the biggie - insulation and R-values to lower their RV weights.
While others simply use different and usually more expensive materials, different designs and engineer in learned strength by applying quite different construction methods, and still keeping the floor/walls/roof thicknesses fairly close to their heavier model lines.
The 2 variations are like apples and oranges and so will their price to purchase almost always. The 2 RV's equal service life and comfort while using will likely have very different scenarios and outcomes especially as the RV ages and so will it's used value as virtually all RV's are eventually sold.
Buyer beware and do your in-depth research and eyeball to know what you are purchasing! Brochure wording can be quite misleading due to words used and facts not in writing or expressed properly. Slick willy is alive and well and looking to pull the wool over the eye's of the unsuspecting or un-informed.
