these are tactical vehicles , not daily drivers, but they sure could be, read the bazzilion threads on there maintenance first, they are one of the longest production run and reliable vehicles ever made, it stands obvious because of how many are running in hobby hands and armies around the world, my first suggestion for allot of use is... tighten all nuts and bolts , this is a major task, i mean all, everywhere, inside and out , at least once, then u should be able to understand what ones will require a wrench every so many miles, like the most important is the jack shaft and rest of the drive train, your question is allot bigger than u might think, there is enough reading on this site to answer all of your questions and your vehicle will be awesome for it, oh and grease is allot cheaper than replacing parts, grease her everywhere all the time, just incase someone thinks hey, they told me it was reliable and i lost my brakes, the drive shaft fell out, and the motor ran backwards when i rolled down a hill backwards in first , and then ran away and blew a hole in her side,and i left her in first gear because my park brake does not work and she got bumped and drove away by herself... well that is all driver/owner error
do not blame the truck, ...good luck.....
