I did notice that the towing capacity is only max of 3500 lbs if equiped with their recommended towing package. Standard axle ratio is 3.21, and I don't see any optional axle ratios available? That probably where they are claiming better gas mileage than a typical Mid-sized SUV. Also, not many colors to choose from.
The good news is that a well equiped Nitro R/T 4X2 with the 20" wheels, Sirius Radio, and most to the goodies is only $26K which includes $600 destination charges.
I'm skeptical since their spec's did not have all the info like EPA mileage ratings, HP figures for both engines, etc.
