The Hall GTC was the brainchild of John Hall, stepson of Airstream founder Wally Byam and former CEO of Revcon Industries. His new venture was called Hall Coach Inc., located in Fountain Valley, California. Designed as an elegant alternative to the cumbersome A and C class motorhomes available in the early 70’s, the Hall GTC was designed to be as great on the road as it was in camping and included a Dodge factory custom stretch chassis with anti-sway bars on both axles, sleek aerodynamic body and well-balanced power package of a 360 cid V-8 and heavy-duty model 727 automatic transmission.
