I thought I would NEVER sell the 03. However a back injury (which focuses pain in the left leg and hip) makes driving the 03's manual trans quite painful. Obviously, I'm switching to the 5 speed automatic. Am also moving up to the Double Cab, so we can take another couple on offroad jaunts, particularly to our WAY OFFROAD "end of the world, off the grid survival bunker" in Arizona's White Mountains.

Was going to go for the 06 Tundra w/0% financing for 5 years. On Oct 1, Toyo announced 3.9% for 5 years on Tacos, which swayed me.

My test drive revealed a much more powerful V-6, faster steering, better handling and a softer TRD ride than my 03.

Only immediate aftermarket option will be a top of the line, ARE shell, to enclose our two traveling companion
dogs, and other cargo. Not interested in lift kits, because it already has enough ground clearance for our needs; and I don't want to degrade the sweet handling.

Short of turbo or superchargers, are there any options that can provide decent power gains for around a grand or less? Any other suggestions for immediate additions that would increase power, economy, or the "fun to drive" factor?

Thanks!
