I have a 1995 F350 with the 7.3 diesel. I'll probably drive it till it drops. It has been pretty much trouble free. I did have the glow plugs replaced several years ago. It starts well in cold weather without being plugged in but runs a little rough for a couple minutes till it warms up. Plugged in it fires right up and runs smooth. It runs 18 mpg on the highway.
I haul a camper with it a few times a year and use it more to haul firewood and saw logs for my mill. It doesn't amount to a lot of work every year but it's nice to have the power. I never noticed that it takes any longer to warm up than the gas rigs I've had in the past.
