You indicated that all 2005 motorhomes on the W24 Workhorse Chassis have the "grade brake". I have a 2005 Monaco LaPalma on the W24 and it does not have this feature....(no switch on dash for this).......???
Is it possible my coach was built on a 2004 chassis even tho its a 2005? How do I tell?
I generally just shift down to a lower gear (on a steep grade) and use the regular brakes sparingly to keep the rpms in a decent range so as not to overtax the engine and transmission (on the premise that brakes are easier and cheaper to repair).
