On an A frame? How would that help?
Front wheels on the road, rears on the frame?
That's what I was thinking....
Then it would be called a "Suspended tow".
I used to have a suspended tow trailer when doing rally recovery. A flat tow, using an A-frame, all the towed vehicle's wheels are on the deck - used one once to bring a friend's daughter's expired car back from Bridgewater to Cheltenham. Got soaked as had to re-rig the thing in the pouring rain after a couple of miles.
Terminology chaps...
