What do you people use. I have 110 in the storage not able to leave coach plugged in.

I also put a battery tender on my chassis batteries at home… I put the negative connection on the post of one battery and the positive connection on the other battery. Works great. I just replaced 8 year old chassis batteries…. And only because of age. They still worked fine…but didn’t want to push it.
