Just saw the new forum, and wanted to jump in with both feet. We have a utility truck that is a chevy 2500 which we purchased at auction from a local utility. It has an CNG system which will allow us to use less expensive compressed natural gas to fuel the truck, and it automatically transfers over to fuel if the CNG runs out. Equivilent to gas, it runs about 1.85 a gasoline gallon equivilent, but there is only 1 public station here. I've considered buying a compresser, special and expensive compressor, which you can put at the shop at it will fill the truck overnight. Has anyone had any experience with these? Anyone run propane, LPG, or CNG on a lawn truck to save fuel or sell their services as a "green" operation?
