I read recently that one should not leave the MH plugged in when not in use. We're on our 5th MH and have always left them plugged in when not in use. If, for no other reason, to keep batteries charged. What do you do?

Keep it plugged in but check batteries monthly

I leave our 96 Southwind plugged in 24/7 when it's parked in the yard.I don't know of a reason to not leave it on shore power.

Always plugged in at home when parked. Keeps house batteries charged and powers the separate charger used for my chassis batteries. Been doing it for decades without any issues. In Florida you never know when a storm will threaten and you have to leave or use the coach when/if the power fails.

Leave it plugged in. The issue that I have heard/read is that non-smart Converters might overcharge the battery. Ours is smart.

Lots of things could theoretically go wrong when plugged in. Fire due to mice chewing on something, breaker trips and your batteries die cause you thought it was plugged in. overcharging batteries and damaging them. Probably more things too. But as long as you have a smart charger, it's relatively safe to do.I leave the motorhome plugged in 24/7 when it's home, but not plugged when in storage (since there's no power there). I've flatlined my batteries with inattention while in storage, never hurt them when plugged in at home.
