Here in the Marcellus Shale gas boom region, they will sell a bunch of those trucks to the gas drilling companies. NG pumps are showing up along the I-79 corridor.
I know a guy who converted an old PU to dual fuel twenty years ago. Of course, he had free natural gas at his farm. Makes real good sense to him -lol.
I also know a guy who has a gas well right next to the family Laundromat. A quarter gets you the longest dry time in the area at their place. They rake in the quarters.
I think the natural gas industry is pushing this initiative. They tout oil independence with a cleaner burning fuel. Of course, they are chomping at the bit to have a market to pump all this gas to.
Right now, the big drilling push is in the wet-gas region. The liquid constituents are the cash cow. (ethane, propane hexane) The dry natural gas wells won't pay the bills. If they go full throttle on the dry gas drilling, I''ll be right in the middle of the mess. As for now, the wet gas is just West of my area.
I have heard many people say that with this new drilling method, the US could become the Saudi Arabia of natural gas.
