Well, after a pretty long search for a new truck, I went a different route than expected and picked up a ranger for a good price. I looked at a couple F-150's and an expedition but couldn't find what I wanted in good enough shape for a reasonable price, so I found a clean '03 Ranger Fx4 extended cab with a loaded interior and 110k for waaaay cheaper than blue book. Guy wasn't using it anymore because he started a landscaping company and wanted a quick sale to keep his company afloat. However, the cheap price came with a few problems. Needed a battery terminal, some grease on the slip yoke, a passenger side outer tie rod, a drivers side wheel bearing is on the way out, and it has a small exhaust leak. It will also need tires soon because of a little dry rot but that's no biggie because I want to upgrade anyway. Granted, the truck still drives with with no real shakes or loud noises, but these are things that are just now becoming noticeable, so I'll fix them before they actually fail.
So far i've fixed the battery terminal, greased the slip yoke, and just did some general clean up. Going to transfer the plates tomorrow, and hopefully get the exhaust taken care of (small leak in a flange between the cat and muffler, shouldn't be expensive). Also going to crawl under and start soaking the bolts for the tie rod and wheel bearing so the replacement wont be bad, hoping to fix both of those Tuesday and Wednesday.
After that it should be good to go for a while. As far as mods go, the truck will likely stay close to stock. The Fx4 package came with 4.10 gears, a stout LSD 8.8, some skids, and it sits pretty high. After all of the problems are fixed I'm start looking for used caps to put on it, so that I can build a sleeping platform. The bed is 6', I laid down in it, and though it's not ideal I think it will do. I'm also throwing around the idea of getting a small teardrop style trailer to drag behind it.
Anyway, thanks for all the help guys, i'm looking forward to getting out in the wilderness again.
