My opinion is that Gulfstream isn't on the high quality side of things. But times do change and perhaps they have improved. I'd look at the floor plan you like then look at other manufactures, and do some comparisons based on price and your own inspection of the units. For example check out the Forest River Wolfpup 17RP and the Desert Fox 21SW for comparisons.
