Our 2500 with a Cummins 5.9 (139,000 miles) is a terrific truck excepting the 48RE and the electrical system, however, we currently need a higher level of reliability to pull a Ranger Tug R-27 cross country. We have no experience with a dully but perceive it to be materially more stable particularly with trailer vertical height of 12 feet. (40 feet length end to end). We ordered the 3500 6.7 Longhorn the this week (21st) excluding the options of a sun roof and winter package.
We have primarily used our 2500 to pull a John Deer 870 with a front end loader and backhoe attachment in addition to hauling materials, and a SA250 pipe welder. We used it to pull the Ranger Tug 250 miles from where we took delivery which went fine, however, it became clear had we broken down, getting to a safe place would be notably more difficult that with our 16 and 18 foot trailers irrespective of how we loaded them. We also have pulled our MasterCraft ProStar 205 with the 2500 which it handles with ease.
Although we understand the challenge of emissions mitigation, we are concerned, however, that with the new 6.7, the DOC, DPF, SCR combination will make the DPF untenable to keep clear. We are also are not clear how the EGR will avoid clogging the cooler which along with a clogged DPF ostensibly will generate enough heat to put the turbocharge at risk. The entire after treatment process is new to us as our 2005 5.9 does not have this system. We have observed although much of the particulates are invisible, if we accelerate moderately up to 2000 RPM it doesn't produce obvious black soot. We plan to follow the the advice of running our new 6.7 Cummins fairly hard every 100 miles or so when not towing to minimize the risk, and hope for the best!
