The inverter will provide 120vac power to outlets that are wired for it. On my Seneca that's entertainment stuff, no fridge, no ac outlets other than entertainment. Jayco's target audience i obviously the family with young kids.
Wish it was different as I prefer driving with propane off for safety reasons and would like the fridge to stay cold. On my class A the inverter drove the outlets by the galley plus one of the fridge outlets (OK, and the TV's).
