I have the same engine/transmission/exhaust brake/chassis as jimbo.
It is obvious that use of the engine brake is subject to a lot of personal opinion. I recognize that many believe it best to use it all of the time, but my preference is use it when coming down the mountain and use the service brakes for normal stops. I've put 60000 miles on my coach (now at 101,000) and the brake shoes look like they can easily go another 100000 miles. I do use the engine brake once or twice on each trip just to be sure it still works.
Some specifics for jimbo on his 330hp Cat/Allison/Freightliner combo:
Your cruise control will not work with the engine brake on unless someone has modified the circuit. Monaco changed to circuit to allow cruse control and engine brake use together in later years, but not the 2000 Holiday Rambler model.
Your cruise control will allow you to set fast idle by either pushing the button on the end of the turn signal stalk, or sliding the switch for resume.
When you turn on the exhaust brake and remove your foot from the go pedal, the transmission will display 2 but this means the transmission will try to shift down when it can do so without over reving the engine. The engine is governed to 2400 rpm when producing power, and 2600 rpm when used for engine braking. If it downshifts and speed increases so that 2600 rpm is exceeded, the transmission will upshift to protect the engine. (You can then get on the service brakes to get the speed down so the downshift can again occur.)
Enjoy your trip.
