More the same as any other EPA2012 Cummins engine. For highway applications, you could get 1,000,000 miles + out of them, provided you do the necessary upkeep. For vocational applications, you should get an equivalent number of hours. Now, if you're gonna have operators who continually cancel regens to the point where the DPF gets plugged so much that the truck derates, that'll reduce the lifespan of the engine.
Need to know which engine you have. The Mack engines (E6, E7, and E9) and Cummins engines (L10, M11, N14, ISL, ISM, and ISX) were available in these trucks.
Approximately 1900 in 2010. Autocar is the leading supplier of Natural Gas Powered vehicles in the USA. they feature the Cummins ISL-G gas engine. Testing is just being started on the higher horsepower ISX 11.9-G Cummins engine in an Autocar chassis.
Saying it's a six cylinder engine doesn't narrow it down at all, seeing as the inline six is the most common configuration for Cummins diesels. The 6BT, ISB, L10, ISL9, ISL, M11, ISM, N14, ISX, Signature, and many others were six cylinder engines, and many of their even larger industrial diesels are, as well. What the valve clearance is... well, we'd need the model for that.
That depends on the specs. There'll be a big difference between, say, a T800 dump truck with something like a Cummins ISL and 4.33 rears and a T800 road tractor with something like a Cummins ISX and 3.36 rears.

Depends on which Cummins engine you have. On the ISL, ISM, and ISX engines found on medium and heavy duty trucks, there are two suspended canister filters on the left side of the engine... keeping the key in the off position, you rotate them counterclockwise with a #2 filter wrench, fill them up with diesel fuel, then you thread them back on, hand tightening them then giving them a 1/4 turn with a filter wrench. Make sure you put some diesel fuel on the seal before you put them on. Cycle the key on and off to let the electric fuel pump prime the system a couple times before you start it back up.
ISL IS A CISCO PROPRIETARY TUNNELING PROTOCOL, BUT 802.1 q IS A OPEN STANDARD PROTOCOL
