Couple 3/4 mos. ago (or so) I/we bought a '98 Northern Lite camper. After deciding and agreeing to the purchase, the selling couple suggested we buy the 2009 3500 dually CTD 4 door 4x4 that the camper was mated to. At first I was reluctant, but the idea grew on me as I drove home. The Ram/Dodge had about 27.3 K (low) miles on it, and was in great shape. We struck a deal on the truck, too, by email (after we got home, since it was a couple+ hours away). We went and picked it (them?) up about a week later.
Since then we have been to SoCal and back for a family wedding (from central WA), and to Knoxville, TN and back. That plus a trip to the Oregon coast, and another to the WA coast, has put 10K+ on the odometer.
More of a Ford fella than a Ram fan, but I am happy with both the truck & camper. The low mileage DEF free truck was too good a deal to pass up. I skipped on the new Ford I had previously ordered.
We'll head to TX in a couple mos., then return home by way of SoCal, and in the meantime my son & family is planning/will be taking it to SoCal, then I'll fly down to bring the rig back home, so it is not a "driveway Queen".... (Retired, so a "Freebird")
I have done some fixing on the camper, and minor mods to the truck. Overall, pretty pleased with the whole package.
CTD is a very good engine, indeed. That engine was the reason I bought the truck.
