My experience with fleet vehicles in rough ( sometimes very rough service, with roads closed, VDOT salt shakers stuck in the ditch with power lines wrapped up in the axles, emergency power company and us only people out in it) the early 90’s Dodge 3/4 tons never failed to carry us through with no drama whatsoever. Could have used some of our escapades off-roading to remote pump station and tank sites for a commercial. Well the early 90’s f-350 460-5speed with the whirlpool in the fuel tank was a close second. The Dodges had the fewest mechanical issues of any of our vehicles. I still believe the only thing tougher is a deuce and a half.
