Since your in NJ do you plan on doing some driving during the winter?
I will drive mine during the winter.
I put my battery tender on periodically. If it's been a 2-3 weeks since last drive (This goes for all year long) I will put my tender, directly connected to the battery, on for a few hours. It typically starts off in charge mode, then an hour so later goes to float. My battery is a couple years old.

I go have a garage but I store my motor home outside (with RV cover) on the grass through the winter. But the tires are up on 2" x 6" so it is up off the grass and so it doesn't sink in when the grass gets wet

Summer tires will flat when parked for extended time (any time of year) so when I plan on a drive, I roll out of the garage and have it sit at a different tire location for some time. Then just drive a moderate pace until they roll out
