We took my '05 2500 on a test run in the outback of central Oregon last weekend (before it all went up in flames) and really put the 2WD to the test...a 25+ mile dirt track over mountains with stream fordings, river bars with loose cobble, and "roads" with deeply rutted spots that freaked the wife out but I loved every minute...she (the wife) was OK once we finally came back out to "civilization" and she knew she'd make into work the next day after all...I carried rescue gear (winch, straps, shackles etc.) but never needed it. I am more than impressed ! 3 days of camping, swimming and watercolor painting...now off to S.F. for a week after the holiday for the City thrill version ! pix soon
