Dolph, your friend is correct, kinda. GMC built coaches WERE fitted with
that miserable 50 amp service cord.
But the coaches that were up fitted by Avion, Coachman, and a few
others, were fitted with 30 amp service cords, and a whole bunch of
different style breaker boxes and 12 volt fuse layouts. Also "BUZZ BOXES"
were somewhat different, as were battery locations. Makes life interesting
when you work on a bunch of different coaches.
