Founded in 1876 after a split from Kaufman County, Rockwall County is named after an underground rock formation that runs throughout the county. Rockwall County began as a small farming community, however the Texas Pacific Railway slowly moved the area toward industrialization. The local economy and the population declined throughout the Great Depression and WWII. However, Rockwall County's fortunes turned around with the construction of Interstate 30 and inclusion in the Dallas metropolitan area. Today, Rockwall County is one of the fastest growing regions in the United States, with over 90% population growth.

Save on Fuel: Propane is a highly efficient fuel source and costs approximately 40% less than gasoline fueled fleet, and 20% less than diesel fueled fleet.
Save on Maintenance: Gasoline fueled engines have far more soot and acids left over after combustion. The carbon and acid buildup contributes to the breakdown of motor oil. After the motor oil is compromised, your engine undergoes more wear. This leads to increased maintenance cost. However, propane burns clean, which allows your motor oil to operate with maximum efficiency.
Reduce Emissions: Propane is a clean fuel listed in both the 1990 Clean Air Act and the Energy Policy Act of 1992. Propane is non-toxic and produces up to 70% fewer emissions than gasoline engines. Many newer propane fueled vehicles are EPA certified as meeting the Ultra Low Emission Vehicle standard.
