I have a 2011 GMC Acadia. Needed room for 5 passengers, their stuff, and supplies for a week. Car top carriers are a pain to load/unload and not as aerodynamic as hitch haulers (my opinion). I've seen these hitch carriers before, so got one. Didn't even know it was there while driving (except it messed up my backup camera when loaded). I had two Sterlite 50 gallon containers (13+ cubic feet total) loaded with maybe 200+ pounds of stuff. I also put tail lights, a license plate light, and a 7 pin connector on it. Total investment - maybe $150, including containers, wiring, lights, and straps. I also bought the cross-rails for my roof rack from the dealer ($195 + tax, ouch!) and installed them, just in case I didn't have enough room, but I did. Only reason why I didn't give the Hitch Haul 5 stars - I'd be nervous putting 500 pounds on it (the advertised max). I'm no engineer, but it doesn't seem that sturdy to me. Two halves held by bolts. Other than that, awesome.
