I'd bet Monaco is looking at IFS. The Roadmaster is, arguably, the most stable of the straight axle front suspensions but I'm not sure it is the best riding due in part to the smaller air bags. Up until the recent past IFS was very expensive, complicated and required front end alignment fairly often. Technology and engineering is closing that gap and I think straight axle suspensions are past their prime and not much more can be done to improve the handling, wander, etc. IFS suspensions are starting to trickle down to less expensive coaches or at least an option.
