Take a look at Fleetwood line, quality and features vary somewhat with model/ price. We have a 2004 Tioga 26Q that has been OK. Most brands/models use same brands of appliances, roof A/C, furnaces, etc. reqardless. Open drawers and cabinets and look at how things are joined, glue and screws, staples, etc. Lazy Daze emphasizes good joinery/cabinetry, roof construction and materials. Expect to pay $10K+ more (new) for high-end rated rigs, may get better price when/if you resell. Roof A/C, fridge, water pumps etc. last about 10 years, regardless of brands. Most rigs are built using high speed assembly, not really owner DIY friendly. Take your time doing homework and negotiate carefully, don't buy on impulse.
