That's not the experience I've had at the Ford dealership. I took my '95 F-250 there when I first got it for a quick once over. They charged me plenty and missed plenty more. Darn radiator was full of Bars StopLeak but the overflow bottle was clean and green - because the small hose was plugged solid. They missed it, I didn't, and I'm not going back.
With time and a shop manual you can normally do a much more careful job. I've now gotten the truck to where I could drive it just about anywhere anytime fully loaded and not worry.
