Battery dead
 

I had the rover parked for about an month. And tried to start today and it was dead. What could be pulling power. I'm sure it is lots of things.
Thanks.

If it where me looking I'd get a total amp draw across the battery and then start seeing which circuits through their fuses (start with engine bay) are alive........ I know, too simple. Yes, it could be anything. If your going to continue not driving for long periods get a battery disconnect (easy) or a trickle charger (outlets/power cords).

Is there an recommend brand of battery disconnect?

Several types to look at to give you an idea.

Battery Disconnect Switches - Electro-Wizard Automatic Battery Disconnect Switch - Combination Battery & Alternator Kill Switch - Combination Magneto & Battery Kill Switch

I'd start with the alternator. A bad diode can drain a battery.

I've got this one on the negative terminal of two different vehicles.

Cheap and just plain works.
A month is a long time to sit. If it were a week or less then I might be concerned.
