There's one guy around town I see sometimes who has some sort of thing that goes on the hitch receiver of his minivan. If I see him around I might be able to ask him where he got that if I remember to. Saw him use it and it too was a non-folding power chair. He pulled up to it with the power chair, pulled ramps down, drove up onto it, pulled himself to his feet using the rear windshield wiper, stowed the ramps and leaned against the van to get to the driver's door. I'm guessing he has some sort of spinal injury.
