fwiw: for the guys who use a maintainer all the time - I think it will mask an aging battery. You'll leave on a ride not knowing the battery only started the buggy with a surface charge, you'll get miles away from the trailer and it'll fail suddenly. Or so you'll think. When in reality, it had been failing for quite a while but that was just an illusion.
I know maintainers have the reputation of prolonging battery life but I'd rather know the battery can hold a charge from week to week without artificial support, that way the battery will fail in camp instead of miles out. If you have a high parasitic draw, a maintainer will hide that too.
Just my humble opinion, as you were -
