2014 Ram 3500 vs Ike Gauntlet

I re-read my post and did an edit, but it should have read, I tow as fast as I care to tow my 5er and merely meant that I may hit 65 mph on occasion in a 70 mph speed zone, but normally tow between 55-62 mph, I tend to get my best mpg at those speeds...(interstate speed limits where I tow run from 50 mph, {I26 from TN into NC}, to max of 70 mph).

Just wanted to clarify:) I'm not in a hurry to get anywhere at this time.
