Thinking about adding a quad cab to the stable. I know its early , but has any pulled with the quad? If so , how heavy, and how did it handle the load? I have a hemi quad now with 3.92 rears, with high flow cats , exhaust, volant air intake. and 04 model, and it pulls our 24 ft race trailer ok, just a little down on torque on the hills. Just figured with the 500 + 500 and the 4.56 rears that it should drag it up the hills as easy as the cummins? Especially maybe with an exhaust and cai upgrade. Possibly with even better fuel mileage? Hopefully the engine torque management on the tranny won't cause too much problem with the pulling. Thanks for any info guys.
