Me as well! My WJ has been very reliable besides the typical maintenance and wear items. The only problems I've had were due to user error.
Change your fluids like clock work and be sure to follow the correct intervals. If you do ANY kind of severe service driving (mountains, towing, dry/dusty, city, extreme heat, extreme cold....pretty much includes ALL of us), follow the severe service intervals and use good quality and the right kind of fluids.
Many disagree but I think the 4.7L is a great engine as long as its not neglected. DO NOT overheat it, not even once, don't even get the gauge near the red. It has aluminum heads that will warp when overheated and lead to a blown head gasket. Been there, done that. Always use the correct oil, quality filter, and the right coolant.
