With a hitchgate, to access the camper, you've got to swing the gate open and leave it open while you're in the camper, right? I wouldn't like the gate left swinging around if it's windy. It also seems the gate would be in the way in parking lots or if you are towing a trailer, which I often do.
When I first saw them, I wanted one, but I'm liking the looks of craig333's setup...as long as the camper frame is up to the task. Additional brackets appear simple to build.
I go with AK...attaching a significant load with five gallons of any liquid at the perimeter of my Hawk and then bouncing and crawling down rocky roads would put a hell of a strain on the Hawk frame and load attachment points...
I actually prefer to not carry any weight behind, to the sides or on top of the Hawk and then pound around off road..
The receiver hitch carrier can be locked open [windy] and yes it does extend the vehicle/camper length when backing up but so does a trailer...tongue length of a trailer compensates for rear extensions of the vehicle or long loads on the trailer [like my sea kayaks]....
Everybody determines their needs and assesses the ability of the FWC to meet those needs...just for me, I prefer to be conservative and stick with a minimalist approach.
