Believe me, some of the lower powered diesel coaches will also struggle on the long high passes, but they will get you to the top and back down. I have had both diesel and gas coaches and have never heard of any coach NOT making to any destination because there was not enough power.
There is a big difference between being able to get to the top and getting there comfortably and gracefully without blocking traffic on the way. We have always had diesel, and a moderately high-powered one, because we prefer to motor along without concerns about either making it or holding up other people.
We had no trouble finding a DP floor plan that works for us, and we get 10 mpg without our toad, 9 with it.
According to your signature, you are comparing a short light Class C with a diesel engine, to what a Class A coach will do in a climb or with fuel mileage, with either gas or diesel. On the long mountain passes that we have driven in the Rockies, there are ALWAYS trucks and other RV's in the right hand lane. Many are there by choice since they see no reason to race to the top and a few are there because their power is on the low side. I am, to use your words, cruising along "gracefully" up to the top. On any long pass that we have driven on other drivers expect to see slower traffic on the right, sort of like the signs say to expect, and it is not considered holding up any traffic. That is what the right lane is for on the long passes. On a usual 8000-9000 mile trip out West for us, I would say that I spend probably around 5% or less of my time on long steep climbs. Certainly not enough to worry about.
