Heck I have a 4x4 Tracker sitting here that runs and is mechanically sound.  Body could use some work.

Don't have time to fix it up myself, but it would make a great hunting rig with a little TLC.

I don't think you would recoup the money spent on a new vehicle, if you intend to keep the Ford anyway. maybe go less often and stay longer, if that's an option.

If I were looking I would look real hard at the Honda Element. You can hose it out after you haul Deer home. The rear seats fold up and out of the way, Easy access and it sips gas.

Eric,

Been down the same road with my Tundra but the numbers just don't add up on an additional vehicle.  Plus I know I'm going to get out of what I might drive into, snowstorms etc...

I say make more of those great bows you build to pay for your adventures and keep the truck!!

I like my Tundra. Pulls my camper great and gets 19 mpg average on hiway.

look under -throttle body-, it is a bolt-on HP and mileage enhancer for gas engines
...and then there are the 'chips' for gas and/or diesel
...the hydrogen thing Skippy mentioned does work..
my F150/302/5spd/4X4, will be sporting some upgrades soon..
Conserving is good, tinkering is American !! and hunting is a MUST..
