Like others had mentioned, Kermit's son often did the deliveries. I heard he would often tow his own vehicle for the return trip.
I have never seen a motor home on a flat bed truck, not sure it is even possible without the use of a loading dock. I would be very concerned of the on/off approach if using a ramp, dragging the back of the PC getting it on the flat bed. For that reason along with all the other good reasons mentioned by other replies, I strongly vote for flying out to Phoenix and driving the rig home yourself. Or have jatrax do it for you. Or someone else you trust.
Heck, depending on the month, even I might be interested. I live 3 hours from the factory. I'd have to rent a car to get there, drive your rig home to you, then fly home to O'Hare airport. Being semi-retired now, I might be available and interested depending on the $.
