I'm starting to plan a 3 to 4 month cross country tour. Backcountry camping and hiking is my main goal but I've become very interested in taking my vehicle into the backcountry. The problem is the truck I was going to take is a Toyota Tundra 2wd - Here is my question... should I sell my current truck or try to outfit it (rear locker and lift). Money is always a concern. Thanks!
