lots of folks have....
I store mine in a lot away from the house too, and when we first got it I studied a good bit on doing something like this, vs the little maintainer panels.
In the end, I installed battery disconnect switches right at the batter lug, one for the chassis battery and one for the house.
So far so good. i store it with the batteries basically fully charged, and with no parasitic loads to worry with, they have so far held up considering the most it ever sits is 4-6 weeks.
