Best diesel pusher chassis ?

10 airbags...Prevost, Newell, Foretravel, Monaco Roadmaster which includes 2004+ Beaver, HR, Safari all on the RR10S for the handling and 9,000+ of CCC. The newest Monaco is NOT on a RR10S chassis.

At this time, there are only four three axle pusher chassis available in the motorhome market, Freightliner (owned by Daimler Benz), Spartan, Prevost, and Newell.

10 air bags? No currently available chassis uses 10. Nor I suggest is this relevant to the "best chassis" discussion.

ZF (Germany) manufactures the most advanced coach suspension systems in the world, and are used world-wide by top-tier coach builders. ZF suspensions are available to the motorhome manufacturers (optionally) with computer-controlled suspension, and active or passive tag axle steering. (Only one chassi/motorhome manufacturer includes either ZF computer controlled suspension and active tag axle steering--guess who).

But back to the number of air bags. ZF independent front suspension has two air bags, their highest capacity drive axle suspension has four air bags (mounted outboard ahead of and behind the drive axle), and their tag axle has two air bags. That is 8 air bags total.

For those wanting 10 air bags, where would the other two go?
