I daily tow a single axle 6x10 covered trailer around 2500 lbs. and a few times a month a double axle dump trailer with brakes around 6-7000 lbs. depending on what's on it. I still have the factory 4:10 gears, I get around 14.5 mpg over all and with no trailer I'm getting 19.5.

I've got a Mopar lift and 35's. I've thought about going bigger, but I tow regularly and it's pretty capable as is. I'll likey keep this set up at long as I'm using it as a daily driver.
