As others have said, there are a lot of factors that come into play on our Western mountains that our Eastern brothers don't encounter. To answer your specific question, it's been years since I went up the grapevine (Tejon Pass) in my current coach. If I remember correctly, I was able to easily make it at 55 mph towing my 4,700 lb Hummer H3. Tejon pass is around 4,100 ft elevation.
More recently, I have gone to Colorado on I70, going over Vail Pass a couple of times. At 11,000 ft elevation, the pass will take a toll on any RV. I was able to keep my coach at 50-55 mph and passing 18 wheelers and other RV's without any problem. And no problem with Donner Pass on I80 in California at 7,100 ft elevation.
In Southern California, I have gone over the Cajon summit (3,800 ft elevation) on I15 in San Bernardino at 50-55 without any problem. I don't try to break speed records on these passes, but keep my speed at the 50-55 mph range which is faster than most RV's and 18 wheelers, but slower than most of the cars.
A DP with our higher HP and higher torque engines can make it over these mountain passes without many problems. And, yes, I have been passed by Country Coaches and Prevost's with their 500 to 600 hp engines and double my torque.
