Yes, the hitch carriers are nice. Makes for easy one-person loading. I've got one (Versa Haul) that we use for the wife's scooter when we travel to scooter-friendly destinations. Have to be careful with the weight on them. The Class IV hitch on my F150 truck is good for 500 lb tongue weight. The carrier weighs 67 lbs by itself, then there's the cantilever effect of the carrier hanging a foot off the hitch. I'm pulling numbers out of the air here, but that 67 lbs hanging a foot out is probably more like 100 lbs just for the carrier. Add the 296 lbs scooter and my carrier is near the max rating of my hitch. The truck does have a noticeable squat when I have the scoot loaded onto the carrier, but it sure makes for a smooth ride with that weight back there. There are carriers that will handle the weight of the Stroms (The Black Widow was one of them at 600lbs capacity IIRC), but it's the vehicle hitch that is the limiting factor. When I was shopping for my carrier, I found online where some of the serious RVers had double or triple receivers on their rigs so they could haul the large road bikes.
I was considering Moto-Tote, Versa Haul & the Black Widow when I was in the market for one. The Black widow checked all of the boxes for me. It was priced the best and had more capacity at 600 lbs. I was thinking for future use in the event I ever got a truck that could carry that much on the hitch. The only reason I didn't get The Black Widow was because it was the heaviest by about 30 lbs and I was concerned about it eating into my hitch capacity. That, and it would be harder to handle by myself.
Moto-Tote was actually my first choice. 550 lbs capacity, and the lightest of the bunch at 63 lbs and it really is a slick looking unit as far as carriers go. They didn't get the business because I had a question regarding the difference in the two carriers they offered, and their web page wasn't really clear. They are an Australian company without dealers in the US, so calling them wasn't an option for me. By the time I received an answer from them via email, several days had passed and I had already ordered the Versa Haul which was a close second at 67 lbs and 500 lbs capacity
It took me a few miles to feel comfortable with the idea of the scoot hanging off the back of the truck, but now it's not such a big deal. Took it on two trips last year; Houston to Key West and back, then Houston to Branson and back with no problems.
Mine came with a hitch stabililzer (anti-wobble thing). It's basically a collar that slides over the carrier tube and has three bolts that are tightened down against the hitch to eliminate wobble & movement. They can also be found on Amazon for $10-$11, and those are just U-bolts with a plate that tightens against the hitch to eliminate movement.
