Brent, the automatic is prone to problems, just like the 5 and 6 speeds are prone to problems. If you were to do a survey, I'll bet the same percentage of people had problems with each of them.
Take care of the transmission, and it should be fine. Be aware of what you ask it to do. Yes, you can tow with an auto, maybe not as much as with a stick, but that's another thread.
I chose an auto for my reasons, you chose for yours. For a good all around performer, I feel it is the best choice, because I do every type of driving with it. Commuting, hauling, long and short trips empty and loaded.
You can do a search and find many threads on the automatic. Decide what you'll use the truck for, and setup your transmission to compliment that job.
Add power mods, and yes, you'll want to do some transmission mods.
