You just proved my point.....maybe you should have read more about how the system works! It's not the end all for Rv's, it's just a nice feature.
You have a very specialized RV and I know they're expensive. Yours is great for hauling a heavy load, but comparing your tractor front end to most RV's isn't really a fair or useful comparison, especially since yours is a niche market with probably less than 1% of the RV market share.
I probably should have worded it differently, but you also took a shot, in a round about way, at the Comfort Drive system.
