Mileage
What kind of mpg do you get with your diesel truck towing and when not towing? Thanks,

We tow a Jayco Eagle HT 26.5 RLS and a Crestliner SuperHawk 1900 behind our 2012 GMC D/A and have gotten as much as 13.9 on a round trip from Lander, Wy. to Grand Teton at Colter Bay, plus a little sightseeing. Last summer we got around 12 towing our stuff. When driving around 70 to go see the kids about 150 miles away, with no wind, we will get between 18 and 19 mpg.
