i had a 90 or 91 f350 diesel dually(rack body dump) and the thing was great for work, mine had the 5 speed manual though. the dual tank hoses especially with the dump body were tricky to fill, but would go fast if you got the angle just right. A 84 f350 dually mason dump i also had(7.3 as well but 4spd manual) was just as reliable for the most part. The 84 started to rust at the cab corners and the floor and even after the injection pump was having issues (wouldnt start cold) we kept running it by starting it with ether in the beginning of the day(yea i know... a no-no lol) but then it would fire right up when warm. We never had any real issues with either. The rad went on the 90/91 in 2003 but thats all i could think of, and yes, they should all have dual batteries.
