Lots to learn then. did dealer mention anything about bi-directional charging?
You may not have that- means the chassis and coach batteries charge at same time when plugged into shoreline power.
Many do not in the Rize and Scope, Tellaro and Sequence models.
So plug into shoreline and every day check the chassis battery level daily- if going down, then you will need to charge that separately with a trickle charger (2-5A) on the jumper posts up front under the bonnet.
Don't let it get past 3 days w/o charging. Unlike Lithium, the chassis battery is lead-acid, and cannot sustain low SOC for very long.
Lots about that in this forum.
Also very likely all your electrics, fuses and cables, buss bars, etc., are probably under the coach with the batteries, just fyi..
Don't be afraid to ask questions, welcome, and good luck!
