40' Newmar 400HP vs 370HP Cummins

Getting close to deciding on a 40' Newmar Kountry Star, Dutch Star or a little older Montain Aire years 2003-2008 (within our budget). The question is: some have 370HP and some have 400HP cummins. Is there a big difference in power/milage/maintenance? Heard conflicting info from dealers who obviously have that particular model. Hope to learn from community experience if possible.

    If the engines were mounted in the exact same MH I expect you wouldn't be able to tell the differance. I think the MHs they're mounted in will make more of a differance then that little bit of HP. Such as the differance in tires, air pressure, wheel bearing condition, rear end gear ratio, do they have the same transmission gearing, aerodynamics, weight, etc.
