I have carried my F650 Dakar on the back of my truck.
I have a Chevy 2500 HD Duramax and Merchant Automotive is about 3.5 hours from here. When I need a Diesel pro, I carry my bike there and ride it back, reversing the process on the way home.
Of course, my hitch is rated for quite a bit more than your hitch.
the Versahaul model that you describe is good for 600 lbs, enough to carry my Dakar. But the hitch-- you are going to be loading that hitch with a lot of leverage. I suggest an aftermarket hitch or a bigger truck. Not surprisingly my truck rides better with the bike on the back of it.
"So what makes this protest different is that you're set to die, Bobby?"
--May well come to that.
"You start a hunger strike to protest for what you believe in. You don't start already determined to die or am I missing somethin' here?"
-- It's in their hands. Our message is clear. They're seeing our determination.
