Winterized and shore power

[Samillet0823]

I have winterized my super c and I am wondering if I should leave unit plugged into shore power for battery maintenance or should I disconnect shore power for the winter? Thanks in advance for comments.

I remove my batteries for the winter and then there is no need to stay plugged in. I put my batteries on trickle chargers / maintainers in my garage. If you are not going to remove the batteries then I would say yes, you need to remain plugged in.

Personally if you have power available, plug it in to maintain the chassis and coach batteries. Removing the batteries on a Super C with 6 batteries is much more involved than a travel trailer and is not necessary.

For years (old Seneca and this one) I leave the rig plugged in and I turn the breaker on and off.
I will turn it on for 2 days and then shut it off for two or three weeks. My thought is in two days it will fully charged both house and chassis batteries. In two weeks they really don't drain that much even if I leave the master switch on. This prevents the batteries from cooking.

This is really convenient for me because my RV is in my barn next to my house.

Just my 2 cents.

Leave it plugged in. It won't hurt it.

I have my 2022 37K winterized in the garage with power. However I plug in for a week, then unplug and turn all power off. When the temps start to really plummet, I keep the unit plugged in to maintain the batteries, extreme cold and extreme heat are the worst for AGM batteries. I have ran this practice on all my RV’s for years, and I get a lot of life out of the batteries…
