If the 8,500 mfr dry weight/ 10,400 GAWR / 940 hitch weight is too much, you might want to look at the LT305BHS - doesn't have the island and a smaller bunkhouse with three bunks - same outside kitchen, double dinette and bath - plus a nice wardrobe slide in the main bedroom. 2 1/2 feet shorter and 2,000 lbs lighter.
The Flagstaff Classic Super Light 832BHIKWS is similar to the OR, but about 900 lbs lighter.
