Imagine you want to go into the motor home business. What formula will you use for your vehicle? How will it be constructed? Will you use a donor chassis? What powertrain will you employ? These are all things to consider and they can make or break the resulting camper. Probably for that reason, most RVs are conventional rear-wheel-drive and are often built on an existing truck or bus chassis with a gas or diesel engine powerful enough to propel the big vehicle up a grade with several people and their gear on board.
Now imagine that it's 1963 and you're the Clark Equipment Company. You make forklifts. You want to make a foray into the growing RV market. Where do you start? Well, forklifts are made of steel and have front-wheel drive. The Clark motorhome was designed with an all-steel body from the ground up, and front-wheel drive to maximize interior space with a low, flat floor free of a transmission and driveline hump. Early models were powered by a heavy-duty Dodge slant six hooked up to a manual transmission. The RVs eschewed a truck's ladder frame in favor of unit-body construction and employed four-wheel independent suspension for a smoother ride. What was this new vehicle called? Why, Clark named it after one of the greatest mass murderers, I mean explorers, in history, the Spanish conquistador Hernán Cortés.
