Your dad didnt have the heavy duty axles, or transfer case. I have a 97 dodge ram 360ci with off road package. It has served me very well, and looks like a million bucks. But, if you are so dead set against Dodge, I had a 88GMC 3/4 ton with ~320,000miles on it when I stopped driving it. It was a great truck. The engine has never been apart, it has always started, and never leaked oil. It has been delegated to Farm Truck status, and assuming I dont need to go over 40mph it will be a great farm truck.
My main problem with the Ford was the body and interior are flimsy. The body is made of much lighter sheetmetal than chevy or dodge. The interior was constantly breaking or rattling, and they couldnt figure out how to make a !%$* cupholder that held anything in. The driveline was good though. You just cant break a 96-97 powerstroke.
