Well, I did a huge major mod to the truck a week ago, and got about 10 more MPG than I had been getting. I did a complete engine swap, transmission swap, transfer case swap, suspension swap, frame swap, and body swap. Completed it all in one day. I swapped all these parts from a 2005 Toyota Tacoma Access Cab 4x4 2.7L Manual. If you didn't know better you might just think I bought another truck.
I will start a build thread on the "swapped" project once I get started on it.
