Spd11, If you can read a factory service manual, you'll be able to do most, if not all of the repair's on your truck yourself. Luckily for most Mud members, the 80 series truck doesn't require a Snap On truck worth of special tools to maintain it. But one very important point to keep in mine, the newest of these trucks sold in the states is now 20 years old, and the last of the 80 series trucks to rolled off of the production line, was made in South America 10 years ago. So Toyota has now starting to tell some of their parts suppliers to stop making replacement parts for these trucks. As time goes by, more, and more parts for these trucks will then become NLA from Toyota. Now you may ask what difference does that make to me. Most Mud members, myself included, think that using factory parts is the best way to maintain them, and it shows, because more then one member here has gotten 3, to 400 thousand miles out of their truck by using factory parts! Just something to think about before you choose, but if it were me, I'd still say what the hell, I'd go with the 80 over the 100.
