trucks, scrapers, and irragation engines, and excavators. the
irragation engines ran at full load for weeks on end sometimes when
their was a drought, in an excavator you fire it up ,warm it up, move
to full throttle and dig holes and ditchs all day. the medium duty
trucksi think in those days the speed limit was 55MPH but not sure.
strrong engine but keep your valves adjusted.

just to see what kind of comments I would get about that chart. I
wish I had enough money to put in a new set of gears for the rear end
so I could keep up with today's traffic but cost wise its just not
worth it. And like I said before when I'm out on the road its not
how fast I get there but just the enjoyment of the rig and its being
built like a tank. Wanderlodges forever!!!!!!!!!!!!!!!!!!!!!!
