I live in south west Missouri and I have been looking for the past 6 months for a good 99-01 used 3500 Cummins 4x4 regular cab and have not seen one for sale. I find plenty of the above in quad cab. Is it just that Dodge did not make that many regular cabs? Also I am inclined to get a 5 or 6sp. based on the problems I've heard with the auto's. I won't be towing or hauling anything near the trucks limits, but it sounds like the autos just quit for no good reason???
