Looking for ideas

I am Jerry Jensen, a new member here. I bought a new '12 Tacoma regular cab 4WD at the first of the year. I have added an Aluminus front bumber, Shrockworks rock sliders, rear reciever hitch, a Delta cross-box and cruise control so far. I carry a 4500 lb. winch on a "stinger."

I am very happy with my Tacoma, it served me well on this fall's deer and elk hunts. Future "add-ons" will be fog/driving lights and possibly some performance improvements.

I am happy with the hiway milage (about 22) but it likes gas off-road. For my uses an auxillary tank might be a good idea? Do air intake systems and/or freeer exhaust system help enough to be worth the cost?

Oh, I am now running 235R85 X 16's which gear it up just a noticible amount. In my dreams a 6-speed with first 4 cogs lower, second about two cogs lower and third one cog lower would be perfect?
