I hauled a '67 Catalina 2+2 from New Mexico to northern Michigan on a U-Haul trailer. No engine or transmission and missing some other things, so I estimate almost 800 lbs. off it's normal weight. I pulled it behind a GMC 5500 and had no problems doing it, at least in driving.
Loading it was a whole different thing. It completely used ALL the ramp area to the point that the rear bumper pretty much obliterated the trailer license plate.
The roller tires went flat on the trip, so the trailer fenders rubbed the doors.
This car had a 121" wheelbase and I know your coach's wheelbase is longer.
Weight of this car taking in consideration of -800 lbs. puts it in the range of 3200 lbs. loaded on the trailer.
My opinion concurs with the others here, have it professionally moved. Or, worse case scenario, make it driveable if possible.
