It's a 750 pound rated cargo carrier for a 2" hitch.
I use a standard ramp to get him on and I will have him ratchet tied down in multiple places to the carrier as well as to my vehicle.
It's a little wobbly but secure. You can see the weight of the engine tilts the frame a bit.
It was 120 bucks at Harbor Freight, no jokes please, and a 20% off coupon brought in home for $95 plus tax.
Now I don't have to wrestle to get him in and out of the back of my Highlander and lean on its side for the ride.
It has reflectors for the back I put on after i snapped the pic, but I may upgrade to trailer lights I can plug into my four port socket. Until I can get a locking hitch pin, I'll strap it to my roof racks or put inside the highlander when at a Rally, show, etc...
It folds up on a hinge like mechanism but still sticks out too far to leave attached in the garage.

It might not look it, but it is sturdy!
