I am thinking about buying a used 2004 Toyota Tacoma crew cab pickup truck. I live in an area where it can snow a lot. Do I really need the 4wd version, or does the PreRunner 2wd get by alright with the high ground clearance. I used to own a 1987 Nissan 2wd truck that would do somewhat ok with 4 sandbags in the back. I am just wondering if the extra maintenance and less gas mileage is even worth it.
