are the cng 6.0 engine trucks dual fuel or natural gas only?? looking to buy thanks
Most of them are bi-fuel (run on both gasoline and CNG, but not at the same time). There are a few dedicated (CNG only) ones running around, but those are rare. I am not sure that there are any '01 trucks that are bi-fuel. The CNG option ran from '02 - '06 and came in either regular cab, extended cab, or crew cab and either 2wd or 4wd. All have the 8 ft bed as the CNG tank takes up the first 2 feet of the bed.
Separate names with a comma.
