Yesterday I started up my '78 Royale, planning on moving it 12 spaces at my storage site. I stepped on brake, pulled the shiftier back, an I couldn't get it to come out of *park* into reverse. It seemed to be locked in* park.*
I turned the engine off and turned the ignition to accessory, no change, still stuck in park. Any suggestions on how to temporally get it into reverse so I can move it? Then what to do to permanently resolve the issue?

Ron,
This is a jury rig, and like any jury rig, it will get you moving but after that.....
As those that know have said, it is probably the cable - that does seem to be the common mode failure. It goes from the column down to the transmission on the vehicle left (drivers) side. With the engine room hatch open and the crew support device (Belly Board) in place, I can reach mine. The cable is connected to the operating lever with a clevis pin and a cotter. Once the clevis is out, you should be able to move the lever - even out of park - by hand. If the coach is not on level ground, either have a helper to stand on the brake petal or at least chock the wheels so she doesn't roll.
Once you can shift it, make a note to get the cable out and lube it or replace it. (Lubeing this kind of cable after it has been seized has about a 50% success rate (in my experience). They are not all that hard to remove and replace.
