Eight foot bed, I hope. $9700 seems like a lot, but the tank is the biggest part and a huge one is needed to get any range on CNG. Compared to what $8000 for the diesel engine option, it doesnt look that bad, assuming you can find CNG stations where you travel. That is what makes it not a viable option on the West Coast where only large metro areas have stations, and distances between them are hundreds of miles.
