I would love a Powerwagon with a Cummins. The diesels are great in the desert if set up properly. I've watched Carli/Thuren set up trucks outperform Raptors at some of the DTX (Dodge Truck Xtreme) meetups. I have to admit. I was close to ordering a TRX though!I will say the day they come out with a diesel Powerwagon im buying it. I know you would need the gas powerwagon for off-roading but how nice would that be a diesel wagon.
