We seriously considered several of the larger bumper-pull Outdoors RVs (ORV) late last year. The standard 2" walls, double-pane windows, and axle shocks, were big plusses. We spent quite a bit of time looking at the entire line of ORV's at one of their larger dealers. IMO, ORV is a step above the competition in terms of build quality, but certainly not a dramatic step above. As noted on several ORV forums, build and warranty issues (some significant) still occassionally occur.
For those considering the longer bumper-pull ORV's, be aware the vast majority of them ship with 30 amp service with no ability to add a 2nd a/c unit. Although they have excellent insulation qualities, one a/c unit may not be enough if you live in (or plan to travel) to hotter areas. Highly suggest the 50 amp option (which includes 2nd a/c prewire) if you have any inclination to camp in warmer areas with the longer units.
Also, FYI, the ORV's hitch-ball height with the off-road suspension is very high. Witnessed a couple folks hitch up their new OVR's with 8-10" risers that still towed nose-down.
In the end, we didn't go with a ORV. We found a Jayco with a nearly identical floorplan (and length) with electric stabs, 50 amp service, 2nd a/c, and 2-year warranty, all extra cost options (or not available at all) on the ORV, for almost $11k less. Cost aside, we would have preferred the ORV, but one can purchase a lot of additional warranty and nice-to-have aftermarket stuff with $10k-$11k.
