Nice reporting Placer,
The Versahaul is a pretty good system. They have a few models. I purchased a used one back a couple of years ago for $275 and I thought that was an OK deal at the time. Anyway, I attach it to the back of our motorhome for hauling two different bikes. One, an '07 TW and the other, an '18 Honda Africa Twin Adventure Sports DCT. Now, for the TW, since that's a mere 278 lbs, the rack is rated for 500 so, I'm real good there. But, when I knew I'd be hauling the A/T on it, that A/T is right at 578 lbs. I don't like overloading things if I can help it so, I augmented the weight carrying capability by adding two more receivers on the motorhome's frame.
Then, I designed some 2"x2" extensions that fit into those receivers. I had to cut and bend those extensions so they would come out, tip up and level off at the bottom of the wheel/tire tray of the Versa haul. In the end, I wanted all three attachment points to carry the same amount of weight. The extensions bolt onto the bottom of the Versa haul so, there's no permeant attachment.
But in either case, we tow our '15 Jeep JKUR so, when we get to places like Moab, we've got the best of three worlds, our own portable hotel, one or the other great bikes, and a Jeep to do things as him AND her.
By the way, the A/T being 548 lbs., could be quite dangerous to load on that Versa haul by trying to push it up on there and keep it stable at the same time. It's phenomenally top-heavy bike. NOT GOOD! So, what I do when I'm taking the A/T along is, I created a portable ramp and platform for myself to walk on and walk right alongside the A/T when it's loading of offloading. Since the A/T is an automatic bike (Honda's DCT transmission) I start it at the base of the ramp and put it in gear. Then, I give it a super slight amount of throttle and at that time, I walk right with it, it going up it's ramp and me going up mine. When I get to the end, the CEO is there ready to apply tie downs to pre stabilize the big beast.
Then the platform and ramp I use is quickly disassembled and stowed away in the coach outside compartments. Sometimes ya gotta do what ya gotta do to have fun.
