Finally got to tow with my RAM this weekend. Part of the reason for switching from my F-150 was the slightly higher max tow capacity and the better mileage.
My RAM 1500 is equipped with the V6, 8spd tranny, 3.55 rear end, towing packge and air lift bags. My F-150 was equipped with a V6 (NOT the EcoBoost), 6 spd tranny, 3.73 rear end, towing package and air lift bags.
It's as close to an apples to apples comparison. In addition to air bags, I use a weight distribution hitch and an anti-sway bar. I was towing my 16' KZ RV Toy Hauler (no bike this time) loaded for non-hookup camping (meaning full water tank) so the weight was around 3200 lbs.
While this was a shorter trip than what we typically take, I can say the the RAM soundly out performed the F-150. Ride quality was noticeably better. There wasn't much in the way of rear end bounce that I typically experience with the F-150. The best thing was the transmission operation, my F150 would constantly jump between gears to maintain speed, the RAM not so much. I attribute this to the two extra gears of the RAM transmission, but it was still very satisfying not the hear the engine RPM's jumping at the first sign of an overpass
Typical gas mileage on the F-150 was around 9-11. I can't really make a good comparison on this with only a single trip, but the RAM averaged about 12 mpg. I try to keep the speed between 60-65mph when towing. I tried keeping up with traffic when towing and that's when I was on the low end of the average mpg.
So, all in all, very please with the results so far.
