Except for the rubber roof and slide-outs (these mean short lifespan) all the other specs look very good.
I see one parked in a campground in the Eagle Ford Shale at Tilden, TX whenever I run through there . Nice lines, nice color and shape especially in comparison to the usual white plastic box.
A MOR/ryde suspension (type not specified) and a decent exterior shape ought to mean decent towing performance compared, again, to the usual plastic white box on leaf springs.
