Introducing the GMC MotorHome. It doesn't ride like a truck. Itdoesn't look like a box. 1. A NEW ERA IN MOTORHOMES IS BEGINNING. Before we started building our MotorHome, we studied every other type of motorhome that exists. We found that the simpler the basic construction, the fewer the problems. So we started with a strong, durable, steel perimeter frame and attached to this a cage of heavy aluminum ribs. On top of this, we bonded both aluminum and fiberglass panels molded to a smooth finish. It's the same construction people are flying all over the world in. Except now you'll be driving. 2. MORE POWER TO YOU. To give you excellent road performance, we installed a 455-cubic-inch V8 engine up front and coupled it to a 3-speed Turbo Hydra-matic transmission. We coupled that to a front wheel drive unit with a 3to1ratioandputitallontopoftorsion bar springs and stabilizer bar. 3. A MOTORHOME IS NO FUN IF IT'S NO FUN TO MOTOR IN. We took our basic construction and raised it only 15 " from the ground. This puts the center of gravity only 37 inches above the ground. For easy handling. See the rear wheels. We put one behind the other for four reasons: To give you a wider base. More room inside. Greater stability than you'd have with dual wheels. And so we could place a special air spring between the two wheels to pass the bumps from one to the other instead of to you! These air springs are the only ones of their kind on motorhomes.
