Depending upon what brand you purchase, superior frame ( built in house are generally better than Lippert)....probably can have a fairly high tow rated receiver hitch, higher rated axles/brakes/tires/rims. thicker sidewalls with greater insulation, dual pane windows, better interior materials/workmanship, better grades of toilet/ faucets/ plumbing, thicker and better grade of floor and roof decking. These are but a few of the items that a “true” higher end unit can/will/should offer! Truly high end units are much more than “smoke and mirrors”, but cost accordingly. Also, generally weigh much more than a “wanna be” high end unit. So now...you must consider a tow vehicle up to the task. Older, well maintained, high end units can be had at very reasonable expenditures! You will have to be diligent in your research, be willing to travel, pass on several (possibly many) that do not meet your standards!
