To me, it sounds like something interrupted the AC supply to your coach and the battery discharged. The AC side of the coach should work with or without the battery in the circuit as AC flows to the main breaker and then on to any sub-breakers and then to your AC outlets/appliances.
The incoming AC is also sent to the converter which then outputs DC to charge the batteries and power the DC circuits/equipment.
I would check the AC supply to the coach. As suggested, maybe you tripped a breaker in the house panel or, if plugged into a GFCI supply outlet, you tripped that outlet's GFCI (it has happened to me).
Maybe try plugging something into your AC supply cord where it connects to the coach adapter and verify power is available there...if so, then maybe check the continuity of your coach 110 AC adapter and work your way towards the breaker panel in the coach.
Hopefully, you can track down the trouble...
