Do you have a Jake brake? Diesels aren't known for engine braking, hence why they sell engine braking kits to retrofit pickups, and why the Big 3 are making a big deal about how they now offer them on the new trucks (like 2009 or 2010 I think.With my XJ on the trailer, the weight pushed through any engine braking in my '01 CTD (NV4500, so no converter slop) in 4th and even 3rd gear. Any more downshifting and I'm going less than 20 mph.
That's in NH, nowhere near as steep grades as CO.
Downshifting can only help so much.
