We're planning a September trip from our home in Alabama to Estes Park CO in our 38' Coachmen Destiny and I'm a bit concerned about handling the descending grade on the return from Estes Park to Longmont in Colorado. Will the 6 SP Allison with 275 HP Cummins have adequate holding for a typical downhill grade in that area? We don't have an exhaust brake and I've not a lot of experience with this coach other than practicing downshifting on local down grades. It seems to hold pretty well going downhill on a bridge crossing the Mobile river with a fairly steep, albeit short, downgrade. An alternative could be to park the coach in Longmont and use the car for the final pitch.
