Don't worry. The only thing I'd do to a runner is put an OME lift on like greg said. They have almost zero ground clearance with gas tank hanging down so low.
I know you love power, but if you were to do it again, would you go with the v8 again? The v6 is plenty powerful for me, but if the v8 is more reliable, then it wins for me.
I'm still not sure what I want, I go back and forth everyday. I've got a guy who's pretty serious about getting my truck, but I'm not much closer to knowing what I'd want. A 4-door tacoma is the ideal rig, but they are extremely expensive and it's hard to spend that much $ on a vehicle I won't drive a whole lot. I'm still blown away how a better equipped 4th gen runner costs $5k less than the equivalent 4-door tacoma.
