2WD vs. 4WD: the unsettled issue of the ages
Wow! I just tuned in to this page. I was overwhelmed by the number and quality of the responses. The issue, however, is unresolvable.
I spec'd a 6 speed, QC, short wheelbase 2wd when I bought my '03. I wanted an economical, pulling machine. The truck has exceeded my expectations. 69,000 miles and phenomenal MPG. At a steady, unloaded, cruise controlled 65 mph on level interstate highway, I recently cracked 26 MPG. (Ramp to ramp, 213 miles) Typical MPG unloaded, non-towing is 23 to 24 MPG. Pulling a 9,900 lb. travel trailer MPG is 12 to 15 depending on winds and terrain. I log all fuel fill-ups, fill to the top of the filler-neck or until my shoes gets soaked, whichever occurs first.
If you want high MPG, that is reason enough to opt for the 2 wd. If your concern is self-sufficiency, i. e. , getting stuck, then wrap yourself in the security blanket of 4wd.
I live in south-central WI where snow and icy roads are standard winter issues. I do not go off-road except for mountain bike trails.
A 4wd is useless for me. However, 2wd's are a "planning person's" truck: plan ahead; don't plan to get stuck.
