Questions on where stuff is - Springdale

[katina]

As y'all are so nice on here and I have looked all over.....I have a 2018 Springdale 311RE travel trailer and have no idea where the circuit breaker box is - or if I even have one. I know - crazy. I'm new to all this. My trailer is parked all the time. The park manager winterized it but now my hot water heater won't work off electric. (switches are all on) I can use gas but prefer to use the electric.

Speaking of - as it's parked all the time - should I disconnect the battery? I read in the manual that if hooked to a power outlet it will always keep charging battery.

Thanks so much!!
