I use a battery disconnect switch. A quick look on Amazon and Harbor Freight yields several possibilities. Suggestions on brands? How much power (I saw 5 watts suggested)? Thoughts on mounting? Any other ideas? Thanks!

If your only interest is in maintaining the batteries while in storage, it's quite simple.
Find any 20-25W solar panel with charge controller and wire. 5W is not enough.
Theft may be an issue. Check the battery water level every 2-3 months. If low, fill with DISTILLED water only. Of, course, keep it clear of snow.
Here's a typical one.
