Ron there is a transmission override switch that allows the transmission to go into gear if there is a problem with the slide. On my '98 it's in the first basement on drivers side where the slide pumps are. Don't know if yours has the same but worth a try.
But hey, we need details on how you managed to use the truck to pull the coach??
At least you're closer to Tom. He can hook you up with Leo and might help solve your problems.
