I agree this is how I look at the cost of ownership. Over a year the amount of extra fuel is nominal compared to the performance of the truck. Like others have stated I wish at least Toyota would have left the gas tank the same size as before. I just grin and bare it.
I have ordered the Peak Suspension Lower Spring Adapter so I can still get and inch or so and still be able to put the Ikon Tacoma, coilover top plate reinforcement kit on for good measure.
