That mach 8 13k has a start capacitor already, that's lucky the Honda starts it , it draws 15.3 amps and 1913 watts at desert conditions acording to the data sheet
The 9200 mach 8 cub draws 11.7 amps and runs at 1550 watts at desert conditions, more likely to be Honda compatable
I wish I kept a "d" series cub like you had on you EC camper off one of my old campers before I sold it, they drew 8.9 amps and ran at 1260 watts desert conds. Do you still have the old camper, the ceiling units would interchange
If you don't mind an extra 5 inches in height coleman makes a mach 1 power saver that draws 9.5 amps and 1260 watts and is 11000 btus
That's what I bought
They also make a mach 3 power saver that draws 10 amps and 1320 watts and is a 13500btu unit
Sucks that you didn't get what you wanted when you ordered the new camper, Id talk to the Dealer and Artic Fox
