well 4x4 you being a Cali boy you should know all about grades, especially with Donner,The Grape Vine and not to mention Sonora Pass the mother of all Grades. Been there done that. Did Sonora pass, but not with an RV too narrow and steep
Sonora Pass may be only the Aunt of all Grades. Probably something like Old Priest Grade is the Mother.
Back on topic: The OP's 29 foot Class C is not exactly a small one ... even when the E450's stump pulling rear end differential ratio is pulling it. Our 24 foot Class C on an E450 can fly up grades, but it does at times take high V10 RPM to do it. Owners not used to demanding high RPM from a truck engine might think that their V10 chassis is under-powered.
