I bought a new 1500 last June and also only use it for towing ( doesn't even have 4,000 miles on it yet ) I really like the way it tows , smooth and comfortable . My trailer is only around 7,200 lbs loaded I considered a 2500 but after driving one I felt it road rough compared to the 1500 and the 6.4 requires premium fuel . I didn't like the look of the standard cab / 8 ft bed and they don't offer a quad cab in the 2500 only a crew cab or mega cab which would be to big for where I park my truck. The diesels are another ball game: the initial cost is a lot more , maintenance costs a lot more , the price of diesel around here is about a dollar a gallon more than gas , and there's the whole DEF thing. As far as power and towing ability they can't be beat though
