Just drove the below old truck with 13k lbs of additional weight with the trailer, bed, and cab loaded with tools and such. Drove 1700 miles in 48 hours, from Tacoma, Washington to White Sands, New Mexico. Scorching heat the entire trip, to include very high temperatures in Western, WA.
Zero issues with the truck whatsoever, except the air conditioning didn't work. I rarely use this truck, so that might have contributed to the no air conditioning. I added Freon in Idaho, worked for a few minutes, by went warm again. Likely a Freon leak.
Why did this truck old truck with 200k miles work well under harsh conditions:
Right drivetrain. Very reliable 2v V10 motor, with oil changes every 2k miles. Very reliable transmission with lubri moly full synthetic trans fluid. And most importantly, a 4.33 rear end. With a 3.xx rear ended it would have been a completely different trip.
I maintain this truck well. It is not used often, but it is a workhorse. Not all pie in the sky. The fuel level monitor on the fuel pump is broken. Ford makes no less than three different fuel pumps for 2002 gas f350s, based on wheelbase and cab. I was able to purchase one of the last remaining OEM fuel pumps, as a crew cab short bed needs a hard-to-find fuel pump. Shame on Ford for having so many different fuel pumps for these trucks.
I have one more trip from Washington to New Mexico. That trip will be in a 2019 f350 dually with a 6.7l diesel. I will be towing a bumper pull trailer. The 2019 has so many features for towing, automatic trailer sway control, built in trailer brake controller, 3" Hitch receiver, trans fluid temperature gauge, I could go on and on. I saved what should be the least stress drive for last.
Grateful for the 2002, but no comparison to the 2019 for my uses.
I think this thread comes down to not is the truck old or new, but what is the truck being used for. Going to get mulch at the local Home Depot, and go fishing later in the day, old truck big thumbs up. Hauling a heavy camper up and down grades, new truck for very many reasons.
Here is my 2002. I updated the interior a few months back with a 2015 f350 center counsel and new seat foam and covers. Updating the interior sure makes.an old truck nicer to drive.
