I've got a 2010 2500 HEMI with 3.73 gears. Bone Stock 15.60 in the 1/4

It gets:
10-12 around town
17 empty @70mph
12 towing my open trailer and Dart @70mph with a bed full of crap.

Good truck, plenty of power but most of it is up higher rpm's, so its going to downshift. Towing to one track we climb through several mountain passes, It likes to climb those hills about 4K rpm in 3rd gear to maintain 70mph up the grade.

No complaints. Yes I wish I had a diesel, for the simple fact you could throw anything bhind it and not think twice. But for me, and the driving I do, financially it doesn't make sense. You've got to put a ton of miles on one or tow big heavy loads to ever see the return.

Tell the dealer you want to hook a trailer to it for the test drive
