Thinking of a class A but have one question about the gen

I carry a Honda 2000 mostly for running power in my cargo trailer. The MH has a propane Onan so in the rare event I would run out of propane I can fall back on the Honda.

It did come in handy one boondocking trip when my LP detector went hay wire and shut off the MH propane. No problem, fired up the Honda and finished out the trip on the little Honda. Since that trip it gets to go every time.
