Congrats!

If the coach needs to be towed all professional heavy vehicle tow operators will know what to do.

The driveshaft has to be removed or the drive axles. Drive axles are sometimes easier to pull. The operator should cover the axle shaft covers with something. Many bolt a piece of cardboard over the opening.

They will also need to supply the coach with air or cage the spring brakes. Air is best and the fitting should be in the engine bay on the passenger side. I don't know if your coach has level low to raise and lower the coach. If the air suspension holds air you're good to go. If the suspension doesn't hold air you need to figure out how to get air in the rear bags. That's easy if the wrecker is using a front wheel lift. More difficult if they are raising the coach from the chassis.

I've never seen a rubber door hinge on a Prevost. Joe's seen more. He'll likely chime in.
