I went east over Vail Pass and my 34' MH with toad went up the hill at 28 mph it is the first time I have done this is this what I should expect from my 2008 V10 Gasser?
Remember not only is it steep, it's a very high elevation too. Combination of the two are hard on any internal combustion engine. Did you notice that even most of the cars were down around 45 or so?
