Looking for an F-150

Hey, guess what?! I'm a GM guy converting to Ford.
Well, not really, cuz I owned an Fox body before my Trans Am I have now.

But I was just wondering. I'm currently shopping around for an F-150 but I need to know what to look for in a truck.
What are the symptoms and problems I need to look out for.
Plus, what have been the biggest expenses for this truck?
It can't be any worst then what I've done to my car.

I've changed the alternator, plugs wires, rebuilt tranny, new water pump, new distributor, new starter. I'm sure there are other things.

So ya, help me pick out a good F-150! I need an awesome truck!
This is what I own now:
