    I'm basically runnin a 2010 Silverado crew cab 5.3l with 7.5" lift, 35" tires w/ 20" XD wheels, no power mods yet except exhaust.. Yeah it added alot to turn over now but only has 3.08 gears for now and getting around 10.5 mpg on hwy.. Whats gonna be better 3.73, 3.9 or 4.10?? Its gonna be pulling the boat (about 12000lbs with trailor) some on weekends but mainly just driving around with it..

    Are you going to be pulling a lot of hills to get it to the ocean or lake? What is going to be your percentage of towing miles compared to not towing?
