Hello. I am putting my RV into covered storage this weekend. Sad but true. I am thinking I should bring my batteries home so that I can trickle charge them once a month. I have 2 12V and one 8D ba...

A fully charged lead-acid battery in at least halfway decent shape with no load will not self-discharge too much over a winter. Self discharge rates are highly dependent on the ambient temperature; a couple of weeks of hot summer weather causes as much self-discharge as several months of sub-freezing winter weather.
If the batteries are stored indoors, it does need to be in a well-ventilated place and if it's warmish they should be on a trickle charger or occasionally given a charge with a normal charger. An unheated shed would be about the same disconnected as sitting out in the RV and should be okay without the trickle charger--but why bother with the effort of moving them in that case?
I don't see any reason why TPMS sensors would have trouble with cold weather. Many many cars and pickups have TPMS sensors and stay outside during the winter and no second thought is given to it, and there doesn't seem to be a big spate of them going bad. Of course, if one is worried about theft or something similar, that's a different matter.
