I drive my 08' 3500 DRW from Talladega to Jacksonville daily, 38 miles each way a averaging 16.9 mpg every other week and drive my 09 Honda Odyssey on the opposite weeks averaging 23 mpg.
Two years ago I purchased the 3500 for $29000. Fully loaded, 108000 miles. Two years later only maintenance has been done with zero repairs needed.
We couldn't justify having just the truck as we use the van for family trips and hauling our two big dogs. Wife drives a Lincoln as her daily driver and she refuses to drive the truck and her drive is only seven miles each way.
