The FZJ80 is an interesting but expensive rig to run around in. I had a 94 that i bought in 2000 with 85K miles. I put 120K miles before selling it and buying a Honda Pilot. They are reliable an hard to break, but when they do break WOW!!!! If you are going to buy one take it to a good toyota mechanic and have it looked at top to bottom. I took mine to a local mechanic who was supposed to be good and got a clean bill of health..... After I owned it for a couple months I took it to another mechanic for a belt and hose change (nasty little hose hides under the manifold on the driver's side)and found a cracked block. we used alumaseal and got another 20k out of the motor before it needed to be replaced(4500$ for used one). I had the check engine light issue which usually turned out to be a clogged EGR vacumn filter which I would replace every 30k. All that being said it was an impressive truck and even stock with stock sized BFG AT tires it went anywhere I wanted to.
A few observations:
1. Gas mileage was usually 13-15 around town or on the highway
2. Never ever let the temp gauge budge above normal. These engines are VERY sensitive to overheating. Even if the needle does not get into the red, but just goes a little above the norm the head gasket is at risk( I learned the hard way. the needle jumped up a little pulling a trailer in colorado and at the next stop there was oil in the coolent. Granted It is hard to overheat these things if the cooling system is in good shape, but watch out.
3. towing capacity is rated at 5000. this is pretty acurate. We towed a 4000 pound travel trailer for awhile in Texas without a problem. After the trailer was stolen we bought a chalet hard sided pop up that weighed about 3000 loaded and towed it from Austin to the Black Hills, over to Glacier and down through Yellowstone, the Tetons, Dinosaur monument in Utah and then back down to Austin via the Million dollar highway and we could maintain 60 on the flats, but the passes would get us down to 45 at times.
Would I own another one.... you bet, in fact I have a line on a 93 with lockers and cloth interior..................
