Fear of Driving to the Mountains

With our 1992 P30 chassis 32' MH the only time I had to use the brakes was on a 14% grade coming out Kingdom Come State park in KY for speed control when it first gear. Never ran into this out west. I think Yosemite was the worse of any place we went on that 8000 mile trip so we never had to use brakes for speed control but used the transmission for speed control but keep in mind the engine braking ability is very high in a big block GAS engine so know your engine braking ability by testing in on a steep grade. Transmissions will up shift to protect the engine if the grade is step enough in gas engine so use the brakes to keep the RPM's below that number. It is some where around 4500 for an older 454 engine. V-10 may be more like 5500 because they red line around 5200 the best I remember. To be safe use brakes to keep RPM's down to the WOT up shift points of your transmission.

Again nothing we faced out west equaled what we found in KY but they are there.
