How about an a-frame hitch attachment point for flat-towing behind an RV?.
The picture is of insufficient resolution, and in very dark shadow to really get a good idea, but my vote is with Mike Hughes’ suggestion. There were towing attachment points on an old Austin I had once, and then we had a frame made to connect to them just for this towing purpose. Alas, it wasn’t behind an RV it was because the cars were notoriously unreliable, and frequently needed towing.
I am not certain that flat towing a Pagoda is all that great an idea…
