Instead of taking a bunch of time chasing down the drain I chose instead to just disconnect the battery.

In addition, when I upgraded the Jensen radio I wired the keep-alive power to the switched coach power so when the unit is in "Store" the radio is completely powered off (the new radio has a GPS so once it syncs back up with the satellites it gets the time so I'm not constantly setting the time).

Since you have a switch installed on battery, it would be easy to put a current meter across the open switch to see how much current is being drawn while in storage. It would drive me nuts not knowing the source or amount of drain.
