running heavy equipment for 41yrs. I wouldn't wast time or money to put a 3208 in anything. The 3208 is the least desirable of all Cat diesels, too heavy for a pu, terrable on fuel, and only 210hp-none turbo. The small Cummins is a better choise.
I have had two of them, (250 HP both with turbos).
Only two problems ever and that was a blown turbo hose at about 160,000 and a bad governor seal at about 65,000, both on the same engine. (1986 model)
When I sold the last truck (C70 Kodiak with a 28" Jerr-Dan steel rollback bed) it had over 345,000 miles on it and still going strong.
I know what you are saying because our local milk company ran them and had lots of problems but I never experenced them.
In all fairness I was about the only driver or was in the truck myself for almost every mile ever put on them.
The milk co has every who ever driving them and we all know how hired drivers can be.
As for the extra weight, the cat is only a couple of hundred pounds more than the old 454.
Granted they are not the BIG CATS on the road but a friend that delivered camper trailers and horse trailers had one installed in a 85 Chevy 1 ton with a Clark 5 speed and it was a horse bact then.
With 20 more horses than the 454 and a turbo it did a fantastic job and fuel mileage was about on par with the 454, around 9 or 10 loaded.
His loads were not all that heavy.
Mostly in the 7 to 12,000 lb range.
I loved my litty kitty cats.
