    I have a 2006 PreRunner TRD Sport with the factory tow package. I will be towing a 22' Toyhauler that weighs 4,600# unloaded, so I will be approaching the trucks towing limits when loaded. My question is, should I change the rear end gearing to make it a little easier on the engine/transmission? How much fuel mileage would I lose when not towing?

    Thanks in advance for any advice.

    Same question. I tow 5-10,000k miles each year pulling 5,000# Travel trailer.....

    You guys that jack the truck all up and change gearing...What gear, gas mileage etc do you experience?

    I tow about 50-60 mph...Normal driving no towing I drive 70mph....

    I'm curious about the same thing. I tow a 2000 lb. bass boat quite a bit. I used to tow the same boat with a 1987 4x2 reg cab. That truck had a 22R 5 spd and it did just fine. The truck I have now is a 98 4x2 Xtra cab, 2.4 5 spd and it seems to struggle a little more than the 87 did. I'm assuming that truck was geared a little lower. My 98 does just fine but it seems to huff and puff pretty hard going up hills. I could also stand just a little more oomph on some of the steeper boat ramps. I'm thinking about changing the rear gear but don't know what's the best route to go. This truck is also my daily driver so I wouldn't want to lose any more fuel mileage than I just have to. Limited slip would be nice too, for those days when the ramp is really wet and slick. Maybe a Prerunner rear end?
