Wow, I can't offer all the pictures, but did own a 2010 and a 2012 Ram's 3500 Crew Cab/long bed, 4X4's, both with 4:10's that I used as daily drivers and towed a 16,000# 5er with that has a 3,300# pin weight......I alway's hand calc mpg....best mpg I ever got towing, (all my towing done in the mountains of WV, TN, NC, SC and VA was close to 11 mpg and as low as 9.5 or so. Best I ever got running empty on a trip was 15-16 mpg...running speed limit, not much over....Towed 5er in my sig with both of the these trucks and now tow it with the 13 Ram in my sig....
again, don't have all the pictures just more facts if you need them or want them.
