I agree that the trailer is the best solution. In absence of a winch you can buy an inexpensive come-along at most any hardware or farm supply store. They have enough cable to pull a car onto a trailer. It will be slow, but that's a good idea anyway.

A come-along is a handy thing to have around anyway, now you'll have one

By the way, if he was gonna tow it backwards with the rear wheels on the dolly, there would be no reason to pull the drive shaft, no matter what transmission he has.
