The old Dodge continues to soldier on for me although it's useful service life, (or need) is far in the past. I can't pull with it any longer as the frame is too weak to sustain the stresses, but it still runs well. Using a one ton dually with V-10 engine is kinda silly to use as a commuter vehicle, but it's been paid for since new and not driving near what I used to, the economy is not a large contributor to operational expenses. Insurance is cheap in comparison to something newer also with the same coverages.
Been looking for a chassis to repower with as the Cummins engines are so popular for other uses, but no luck as of yet. Mine is rusted so badly I can't graft the front, or rear to something else.
