RPM, it is a 4x4, works great too. It just looks like it is sitting low because there is about 10" of snow next to it.
I can't remember the exact #'s but I think it has around 350 hp. I know it has way more balls than my old chevy with the vortec 5.3 v8.
The trucks I test drove before I bough this one are:
The super cab ford F-250 with the power stroke and the v-10, ok trucks but not worth $40k.
The chevy 1500 extended cab, still the same as old with new face (IOW a POS)
Ford f-150 super crew cab (2002 used) Felt cheap and poor crash test ratings.
The Toyota Tundra Double Cab. By far the best truck, just too much $$$$$.
This Dodge 1500 quad cab with the 5.7 hemi. 2nd best truck, $10k less than the Toyota. Got it for $25, 900 with a 7 year, 100,000 mile bumber to bumper waranty. it currently has 124 miles.
