I hope my gut feeling about that truck is wrong, and it turns out to be a nice rig for you.
On the 2x/4x fight I started, here's the disclaimer first: I currently have 2 4x4s here. One is my woodhauler, bought it cause the price was right, not because it was 4wd. The other is a plow truck, and has a real need for 4wd with that much steel hanging 5' in front of the axle.
Now back to what I said, "a 2wd with a locker" - not a one wheeled wonder or a limited slip that may or may not work when you want it to, is a very capable rig off road. I never said it will go everywhere a 4x will, but it'll get around pretty good. Those that have never driven a true 2 wheel drive would be surprised. I've pulled loaded gravity boxes out of rutted field driveways in a 2wd, climbed some steep hills on sandy ground out in the woods, and pulled a few cars out of snowbanks with one.
You'll also save about 400lbs of empty weight, and especially with the newer trucks without lockouts, not waste fuel spinning transfer cases, front drive and axle shafts, etc. and get a bit better mileage because of it. My one beef with 2wd is a lack of ground clearance, but that's curable if it's a big issue.
