Hipower stated:The Navistar engine line would seem to be well proven in their OTR truck products and if the HP/torque curves fit in an RV application it would seem to be a good alternative to Cummins, Cat and Detroit.
I don't know where you got that information. Those engines are far from proven and came very close to killing Navistar's engine mfg.! The truckers hated the engines and finally Navistar smartened up and is installing Cummins. Neither Cat nor Detroit are supplying engines to RV mfrs. Cat does not sell any OTR engines other than something for specialty uses. Detroits may be used in some bus conversions. If the new owners expect to sell any units they will have to dump that ridiculous excuse for a powerplant. I do hope they continue with the Roadmaster but the last link sounds like that too will be history. I bet most in this forum do not know that the Roadmaster chassis was designed by Chrysler just before they went bankrupt.
