I can't say which is my best... I've had alot I've liked, hard to narrow it down to one.
I had an '86 s10 2wd 4cyl/4 spd, paid little for it, myself and others ran the guts out of it for years and couldn't kill it... on of my buddies used it to haul a 275 gallon water tank (over a ton) to his house on top of a hill... my dad drove it a while... great little truck.
I have (currently in storage) '88 s10 ext cab 2.8 v6/5 spd 4x4, it will go d@mn near anywhere I want it to... needs a clutch, I'm gonna give it to the kids to drive in a few years.
I ran my '84 k30 in the mud a few years, then as a work truck, then back to mud truck again... people knock the ol 6.2l diesels, but I put 40k miles on it with no issues. Beast off road too...
I like all of my superduty based 7.3's, the Excursion has been trouble free for the 50k miles we have put on it, has 292k total. My dually has only needed a transmission shortly after I got it, but having put over 80k miles on it in the past 10 years, no complaints. My f250 is my favorite, despite the current need for a motor, having a 6spd trans, ext cab short bed makes it 'all that' for me.
