 Bought the vehicle new, V8 with TRD package. It came with a 3" lift kit and 20" rims from the dealer. I'm averaging 16 mpg. The odometer is off by .1 and the odometer by 5 mph due to bigger wheels/tires. Plan to try K&N air filter and maybe a performance muffler such as Flomaster. Overall the truck handles well and is fun to drive. I have as good or better ground clearance than stock 4x4's from other manufacturers. I replaced the radio/CD player but kept the stock speakers as they sound pretty good.
