    as you guys know, i drive a milk truck. its a 2010 kenworth T660 with a cummings ISX and an 18 speed trans. i noticed today when i was pulling a heavy load (the milk weight alone was 65K plus the weight of the truck putting it over 90K gross) up and down some fairy steep grades, my regen light came on and stayed on until i got to the yard. when i got to the yard and dropped the trailer the light went off after a little while. usually i drop that trailer, take a short bob tail ride to another farm 2-3 miles away and pick up their loaded trailer and drop that at the loaded yard. we have two yards, a loaded yard and an empty yard.

    anyways my question is, does the regen cycle more or even run continuously under heavy loads? this truck does not use DEF fluid.

    You should call a Cummins center and speak to the shop manager about it. That's the horse's mouth.

    The more fuel you burn the more regens it will do going down the road. You usually can't tell because it only shows a hot exhaust light if you stop when it regening while driving.

    If it didn't Regen good or did not get hot enough while driving, you might get the Parked Regen light. So it can raise the emissions box to 1,000F and clean the DPF better.

    Your truck is 7 years old. The DPF has to be pull out and cleaned like every 300,000-500,000. Plus you have the two doser valves that injected diesel into the exhaust. One is by the turbo for regening while driving. The other is by the DPF filter for a parked Regen. The one by the turbo get lots of carbon build up and stopped working or drips diesel into exhaust vs spraying it and it won't Regen while driving. So it could be any of those thing not work correctly.
