I loved my Ranger when I bought it. It had under 65,000 miles. It was great to drive and was great off road. The rear doors would rattle a lot even though they were closed very tightly. Only problem is after a week of owning it, I had to take it into the shop already. The rear wheels constantly lock in place. A problem for most owners of the Ranger. It was in the shop at least 3 times for that issue. A few months later it was in the shop again for the transmission. Out of the blue the transmission blew a gasket so I lost third gear. Apparently another common problem.
4x4 is great off road or in the snow. I loved the 4.0L V6, and the interior is very nice for a truck.
Take a look at a new transmission, and look at the design of the rear wheel drums/brake System! Look at ways to stop rattles in rear doors.
