Lug_Nut, I don't know where you get your info from, unless it's just speculation. Most Roadmaster owners I know like their chassis and none have wished for an IFS. I have owned Freiightliner non-IFS (Phaeton), Dynamax IFS (CC) and this RR10S Roadmaster and I like this chassis the best. I don't miss the IFS. This chassis has no nose dive on stops, no rocking back and forth going in and out of parking lots and handles curves like it was on rails. The CC had a great soft ride on straight roads,but with four inside air bags it would rearrange the cabinets if we didn't slow way down going in a parking lot. As for tires, I assume you are talking about 315's. If so, how do you figure the difference constitutes the remark "undersized tires". We're very happy with Roadmaster. If they can improve it, great, but if not, like Logthumper said, "If it ant broken, don't fix it."

Bruce, Actually I have heard it from several Monaco owners, that they want IFS and, in two of the cases were prepared to look elsewhere if necessary. All the other chassis manufacturers that have developed and offered IFS, did not do it to waste money, it was due to customer preference. Monaco is, and has, lost sales due to lack of IFS, and yes they will be offering it sometime in the future.
295 tires are marginally acceptable on the front end of a 46k GVW coach. At the price, why not put a 305 or 315's on instead?

Lug_Nut...I'm not trying to hijack Roamer's post....I guess this is all on topic to answer his question. I was concerned about leaving CC's IFS and smooth ride. Didn't have any choice because we decided on the Beaver after 8 months of shopping. Over a non-IFS chassis like the Freightliner I had, the IFS is a huge improvement, especially going over parking entrances and speed bumps, etc. I really believe this Roadmaster takes the bumps, etc better because of less rocking with the outside air bags. I don't feel any pull in the steering wheel and normal driving is much more stable. Now, I do have the tag, and I don't know how much difference it has over the non-tag chassis. I know going down the road it has a big difference on stability in wind and passing trucks. I agree with you that buyers want the IFS over a non-IFS chassis on most chassis's, but I feel the Roadmaster is fine the way it is. And if it's stronger with less moving parts, it may be better off keeping it the way it is. I'm not an expert and it would be interesting hearing from more owners who have owned both Roadmaster and non-Roadmaster chassis's.

Good point Bruce. Perhaps whenever they develop one they will make it an either or option.

I came from a Freightliner to this RR8 and in my opinion the only advantage of the previous chassis was the much sharper turning radius. I'll do without that any day for the ride and handling of the RR8. Every time I drive this thing I get excited and feel like I am being coddled. The wife also cannot get over how much smoother and quieter the ride of this coach is over the previous one.

I have to admit, the RR8R chassis with the 8 outboard air bags is a very stable platform and provides superior stability and handling than I have experienced in some other coaches. That said, IFS has the potential to be a better front end design than a straight axle front end but I don't think the current mid-price DP offerings are any better than what Roadmaster has achieved. While bump steer has been eliminated and generally a better turning radius I think those advantages are out weighed by the increased cost, ability to hold alignment and service cost. Straight axles have been used on large vehicles for a long time because they are tough, hold steering and tracking geometry and are easily serviced. As engineering solves the cost and reliability issues with IFS suspensions they will replace straight axles. JMHO

Good points....Happy New Year.

And Happy New Year to all!
