Storing TT away from my house--maintain battery?

Thank you everyone! Very helpful info.

Matt-the storage area is well-secured, fenced with a gated entry. Of course anyone storing at that location would have the gate code...

I will look into solar (I don't plan to use their interior units) as well as battery tender and a cut-off switch. I'm sure I will find what best fits my needs. In the meantime I will do as one suggested, disconnect the positive cable as I do have some parasitic draw.
