Nothing that I would consider serious or unusual. A problem with the hydraulic clutch cylinder was repaired under warranty.
This was the best truck that I have ever owned!
I could get from LA to San Francisco on 10 gallons of #2 diesel, a 405 mile trip! Nothing I have ever owned before or since could get this kind of fuel economy.
The engine ran 150,000 miles before I had to do anything to it, then it was starting to use oil. New rings, new rod bearings (the mains were still at factory tolerance, so I left them alone) and it was as good as new.
The only downside to this truck was the noisy ride. With the heater blower running while driving at freeway speeds, the sound level measured 85db (A weighted).
At 175,000 miles, the transmission started making worn bearing noises, and the rear wheel brake cylinders were starting to leak. I would have repaired these items and kept this truck going if I did not need four wheel drive. I still sometimes wish that I had kept it.
Could you mean 1982 for the year? 720's and SD22 engines weren't introduced until 1980/81...unless maybe the truck you had was a 1972 620 with a diesel engine swap?
