Any updates?
Sorry, I should have returned to follow up. Yes, I got it and it works very well for my MiniST - all I did to mod it was drill out the pop rivets under a supporting bar at the rear wheel so I could shove it forward, allowing the rear tire to drop lower into the carrier; compare first and second pics below. My Mini weighs about 89 lbs after the accessories were bolted on, but the carrier is rated to over 350, so that's no problem. I can just drive the bike onto and off the carrier with the ramp, using the motor in "walking mode" and standing at ground level - easy to do. My driveway slopes down to the street, so I park the truck at the bottom, which puts the carrier lower to the driveway surface for a more-gentle ramp angle, as shown in the pics.
I cut the tiedown straps to length once I was sure where they needed to go. You want to make sure to lock out the front suspension before tying down, to keep it from bouncing loose in front. The black bar is from Hollywood Racks, to adapt weird frames to hanging-type carriers, but it was useful to create tiedown points as well. Surprisingly difficult to find this bar online, but doable. Once all the tiedowns are cinched up and the receiver anti-sway clamps torqued down, the entire assembly is solid and doesn't wiggle.
Also have a cover and large cargo net to lash down the cover for carrying in wet or dusty weather over long distances to keep the bike clean, and add-on turn signals if needed. Let me know if any more questions; I'd definitely recommend this carrier as an inexpensive single-bike option.
