    I have an issue with my KW 2023. It has an epu that runs your ac/ appliances on an auxiliary battery that is charged while the truck is running. Cool! While you sleep the truck starts itself to recharge these batteries.

    The issue is when the truck is off the auxiliary drains super fast! And the truck starts in the first hour into my 10 reset and never shuts off because the auxiliary takes FOREVER to charge. Leading to my fuel being wasted all night which upsets me.
    Anyone have any tips on this matter? Thanks

    Maybe get the auxiliary battery tested? Seems like it is not holding a charge.

    Or the charging circuit has an issue

    Microwave doesn't use any power unless you are using it. Miniscule draw if it has an LED display.

    Batteries. Probably good idea to get auxiliary and mains tested. It is a bit of work to do, If it has skirts, they will need to come off to do this.
