I'd think that your axle ratio is very key here. The Ram website shows the 2014 V6 has max tow capacity of 4,800 lbs with a 3.21 rear, and 7,300 lbs with the 3.55. If you have the 3.55, you'll probably love the towing ability of your Ram. If you've got the 3.21, my guess is you won't be satisfied.
I have a 2013 Ram Crew Cab, hemi, 6-speed tranny and a 3.92 rear. Max tow capacity is 9,900. I pull a 4,500 lb empty weight trailer, and have absolutely no problems. Average mpg is about 10, cruise control holds speed most of the time; I use tow/haul in hills, otherwise its off (eco mode doesn't kick in if tow/haul is on). Just returned from a 4,000 mile trip from Albuquerque to Yellowstone, to Glacier National Park. The only time I was worried about the tranny temp was going up a 13% grade heading into Cedar Breaks National Monument in Utah (hwy 143) and the temp hit 198 - normally runs around 160.
