Ken.....Call or email Monaco as stated in one of the posts. They will give you the ride height numbers for your specific coach. The front and rear will be different. Provide them with your coach build number.....should be a six digit number located in a couple of spots in the coach, and ask for the build card. They will send you a two page list of everything that was installed in your coach, including serial numbers.
The ride height is adjusted by airing the coach up on level ground. The ride height is measured at the airbags. There is a 1/4" plate on the top and bottom of the air bag, holding it in place. The measurement is taken from the under side of the top pate, where the airbag touches, to the top side of the lower plate, where the air bag touches.
There are two height adjusters on the rear and one on the front. Adjust both rears and then adjust the front. Dump the air and then air back up, roll the coach forward a few feet and recheck the measurement.
The best and easiest way to make the actual measurement is to make a banana shaped tool out of a piece of heavy metal rod. Bend the rod so that the measurement between the two ends, equals the distance required, such as 7 5/8". This allows you to easily slip the tool over the airbag and between the plates.
I found a pair of calibers made in an arc and noted the front and rear measurement on the side in a Sharpie. I checked mine once a year.
There is a rod on the height adjusters that is loosened and then slipped in the direction you need. Only slight movement is necessary and wait for the coach to add or subtract air, to see how much it moved.
As always......when working under the coach on the air system, have safety stands.
