In 1956, Yellowstone considered various proposals to modernize their White Motor Company Model 706 Buses. Proposals ranged from engine and power-train replacement to total overhaul and rebuild. One tried idea was the placement of a Model 706 Bus body on a 192-inch wheelbase Ford B-600 school bus chassis powered by a 168-hp, 8-cylinder engine. The thinking was the more powerful engine and modern running gear would improve performance and cut maintenance costs while the open-top body would preserve the look and feel of the traditional Yellowstone bus. Needless to say, the bus had suspension, transmission and carburetor problems plus its overall appearance was lacking. Although the problems were eventually worked out, the costs were too high and the proposal to modify the Model 706 buses was rejected. ​

Numerous service vehicles were used in Yellowstone National Park over the years such as  Water Trucks, Tow Trucks, Supply Trucks, Telephone Service Trucks, Dump Trucks, Fuel Tanker Trucks, etc.​
