Until this week, my TV was a 2010 Silverado 1500 with a 5.3 and 3.42 rear end with 6 speed automatic. I tow a 6400 lb empty, 8200 gross weight Starcraft with an 1100 lb tongue weight (on average) using a Reese 1200 lb dual-cam hitch setup. The truck has made 2 trips to FL and last year it went 7200 miles on a trip from Western New York to FL to TX to Phoenix and back home. Except for several legs with headwinds, I averaged 9.2 mpg. With headwinds or steep grades (up) expect the mileage to drop to around 7. I was planning a trip to SD in this truck this summer, but came across a 2500HD that I couldn't pass up. The 6-speed transmission makes the difference. I owned a 2005 with a 4-speed auto and 4.10 gear ratio and the 6-speed out performs it by a mile.
