I have the standard Hitchgate (offset) and it has proven itself to be 100% reliable and so far been worth every penny. My options for a swing-away bumper were limited (as in none) given the camper on my truck. My only other option would have been a full custom swing-away bumper. I have nothing but good to say about the Hitchgate. It's now been on the truck for close to 40K km of travel, including thousands of miles of bumpy forestry roads, up and down the Dempster, and many off-road trips.
I also recently bought us a couple bikes, so I've now added a bike rack to the spare wheel and can tote our bikes around with ease. This set-up has also proven itself solid and reliable (I do run a seperate strap from the truck bed to the bike rack....just to keep my paranoia in check with our "new to us" bikes on the rack and I dont run the fuel tanks on the Hitchgate at the same time as the bikes...to keep the weight down).
