Dehumidifier operation on 120v in storage

[Jdpyle]

We have a AS 2018 27’FC and I keep my AS in a fully enclosed storage year round. We live in the Houston Tx area and during the winter period ( Nov-Feb) I keep a 120v dehumidifier (DH) plugged in to one of my receptacles while everything is closed up to keep the humidity levels down inside the unit. I keep my unit plugged into a 15 amp 120 power to power the DH while it is in storage. To power the unit from the receptacle it requires me to keep the shutdown switch “On” throughout this time. Will this harm my batteries or any other electrical gear, chargers, inverters etc. even though I am sure my onboard charger just keeps a trickle charge on the batteries while I am hooked up and in storage?

I keep a dehumidifier in our 26u and have done so since new. The only problem I have is that when it gets cold, the dehumidifier shuts off. The AS is under cover but is outside. I’m not sure at what temp it cuts off but it does continue operation when it warms up.
I keep the AS connected to power and have the dehumidifier plugged into the kitchen outlet.
