Got a new toy today (to me anyway, its a '72).

Still getting used to it but definitely a blast to drive.
Over 10ft tall & over 20,000lb. You actually look down at tractor trailers when you pass them on the road.

Its a 5ton AM General

Gets about 5-8mpg depending on how you drive it.
I can see the $100 in fuel I put in today is not going very far.

Has an 855 ci Cummins (no turbo) w/ 5 speed & 2 speed transfer case.
Have a turbo for it, when I get ambitious. I could use some more power.

Axles are 6.44 geared Rockwell's.

Tires are 16.00R20's 53" tall.

Peaks at about 65mph.

Most Non turbo N series Cummins don't have piston coolers, so if you add fuel and air think about the jugs and slugs. But unless you get the tank to pull behind it you wont hardly open the thermostats. Its a nice truck i like the big tires all the way around vs duals.

Sweet. I always wanted one of those. There's a couple of those that come out to the mud bog park. They're newer though I believe, I can hear the turbo screaming. They'll drive them out, torture them all day long in the hole then drive them home

Yes I'm told you can only increase it about 50hp safely.
I would like to clean up the smoke with a little more air.
It even smokes on the level at cruise speeds.

The newer ones have a 500ci turbo engine which is a little better on power & fuel.
I wanted the old style nostalgic military look that these have.

It runs in the 150 range on the gauge from what I can see.

Looks like I may have to pull a fuel tank around for it instead of a military tank.

Previous owner took it down the track 30.2@44mph.
I will not be racing anything for sure.

Kind of anxious to drive it in the snow to see how it goes.

Still need to clean the tires & apply about 3 bottles of protectant (hopefully 3 will do it).
Don't want to buy another set of those for sure.

That thing is sweet. Love to have one just not sure what I would do with it. We had 3 or 4 of them where I worked in Socal. We used them as water trucks damn things would go anywhere.


There is one for sale in Orange, TX even has a trailer with it. I'll have to snap a pic when I get off. I think the guy selling it lives down the road, because there are 3 duce1/2s siting in his yard.
