I just bought a 2015 Dodge Ram 1500 eco Diesel crew cab with 3:55s. Of course, I did my homework after I bought it and found out I’m right up against the towing limits of my camper which is 6200lbs. Dry. On the door of the truck iI find that the GVWR of the vehicle itself is 6900lbs. I looked up the GCVR (what it can tow including the weight of the loaded vehicle) and it’s 13,700 which leaves me only 6400lbs. Of towing capacity for my 6200 lb. dry weight trailer. I’m moving on from a 2002 Chevy Suburban with 3:73s. (270hp, 321ft. Lbs of torque). The dodge is rated at 240 ho and 420 ft. Lbs of torque. I was thinking 100 more fr pounds would give me a lot more power to tow than my suburban did but now I’m second guessing. Haven’t towed the camper with it yet.
