You should be able to find a pretty decent 4th gen for under $8k. We have a 3rd and 4th. 4th is the stock daily and the 3rd has 3" lift and 33s. I like the 3rd more, BUT, 4th is so much more comfortable to ride in. Its a limited with full time 4wd and the 4.7 V8. Personally, I had rather have it than the 4.0 V6. Both are great engines. Really no advantage of one over the other than I just prefer the 4.7. You do have timing belt maintenance on it though and not the 6. Also with the Limited you get the power seats and heated leather. Again, just my preference, but almost infinite adjustment and well, nice and warm. Check for rust on both. Frame rails and around the lower radiator supports. Get under it with a light and check, check,check. Check the rear brake backing plates on both for signs of gear oil. Axle seals leaking are pretty common. 4th gens are also prone to calipers seizing up. Make sure it rolls freely with the brake off. 4th gen, make sure the transfer case goes into 4wd and 4wlow and back out, especially going in and out of low on the full time 4wd version. 3rd gen 3.4 engine is great. Also has timing belt maintenance.The 4.0 V6 in the 4th occasionally has head gasket issues. None of these are things to be "scared" of, but just be aware of when shopping. Actually, it may possible to find a nice 4th gen for less money than an equally nice 3rd gen. Go figure. Cult following on the 3rd, maybe worse than that of a 1st gen.
