What a difference a HEMI makes.....
Wow, what a difference in towing the new (to me) 2013 Ram 1500 5.7L Hemi makes over towing with the 2004 5.3L Avalanche my wife and I had! We figure, loaded out 28DBUD weighs in between 6700 and 6800 lbs. You can feel it when you get it going, but overall, no butt pucker factor.
The OEM brake controller is smooth and functioned great! I have it on Heavy electric with the gain set to about 3 and it seems about perfect.
While no one should ever take towing lightly, the overall experience of towing with an actual capable rig was dare I say, enjoyable?
