Yep, the truck has a 9.2L (555 CI) Cummins V-8 diesel engine hooked up
to a 4 speed Allison automatic tranny (soon to be replaced with a 5
speed auto) and that is how it came from the factory. It's a 1975
Dodge XCNT800 tanker truck with a 58,000 pound GVWR. Below are a few
links to some pics of it. The first shot shows the truck as it was
when the seller I got it from first acquired it. Since then he has
removed the tank and the truck now looks like what is seen in the
second and third pictures.

It has been used as a stationary refueling point since the county got
it from the military back in 1993. The engine was never run (they used
an electric pump setup to transfer fuel out of the tank in to trucks)
since they got it so the truck only has 9,000 miles on it.

Since I can't have a truck that long in the base housing unit I am in
I most likely will end up cutting about 12 to 14 feet of frame off the
back and putting a single rear axle under it. Don't know yet whether I
will put a flatbed on it or a fifth wheel plate and make a tractor out
of it. After that I might look in to replacing the Cummins 555 with a
turbo'd Cat 3208 for even more power. <g> The Cat 3208 is what
replaced the Cat 1150/1160 engine that Dodge used from 1973 to 1975.
