Your chassis, built by Monaco, was called the Roadmaster Chassis. It was Monaco's proprietary chassis. The handling was improved by moving the air bags outside of the frame, versus on the frame. One bag in front and behind each tire. They also had a shock absorber associated with each airbag. They handled well, but were a little stiffer riding than other coaches. Their main chassis was called the RR8R. They used the 10R chassis when the coach had a tag axle. They also produced an R4R chassis that was pretty similar to those on other brands. It came with their entry level DP, but had issues with the trailering arms breaking (arms that hold axle in place) over a few model years.
When Monaco went out of business in 2009-2010, the company was sold to Navsitar who kept the chassis, but started substituting their motors. When they sold the company for a second time, the Fleetwood parent company bought them and ended the Roadmaster chassis. They built a new line, still calling it Monaco, but on a Freightliner chassis. In my opinion, that was the end of Monaco. The only good news is that through both new companies, Monaco parts stayed open.
There has been a report that the Beaver line of coaches, bought up by Monaco many years ago, is going to reopen in Oregon. It will be interesting to see what chassis they use. Even though the Roadmaster chassis was a good chassis, it was long in the tooth and ready for some revamping.
