I have the R/T and obviously love the power. It is only rated for towing 2,000 pounds, but I've towed well over 3,500 pounds without any problems running the air conditioning full blast while driving up the mountains in the summertime. However, I've had lots of electrical problems, and the truck has broken down on me in the middle of the Arizona desert. In addition, I get 12 mpg in the city and 15 on the freeway.
