I tow a 6000+ lb trailer with my 2015 Ram 1500 Quadcab (5.7L, 8 speed, 3.92 gears). It is an absolute pleasure. Night and day difference from my old '97 F150. Towing in the northwest is a liberal mix of flats, hills, and mountains. It handles all of it with complete control. The integrated brake controller is the smoothest I've ever used. In the past, my trailer brakes always tended to be a little jerky, not anymore. I have power to spare, and am even easily able to pass a line of vehicles while climbing a mountainside with power to spare. The vehicle is very quiet during normal driving, but sounds nice and throaty when you get on it. There is no annoying drone while towing. Truly an absolute pleasure. My available payload is around 1400, though I don't remember exactly. With the GAWR of 3900 lbs, I have a huge cushion if I choose to exceed my GVWR a little. Even the OEM P rated tires, when aired up to max, perform excellently. The only possible drawback in my view, is the soft suspension. I recently upgraded the rear springs with progressives, which still feel the same unloaded but stiffen up quickly as a load is applied. In case you couldn't tell, I am very pleased with my Ram.
