Where to mount solar controller

I just bought a Morningstar solar controller for a little 15W solar panel I have on the roof of my Sunseeker 3100. I figure it will help to maintain both the motor home battery (in the winter) and the house batteries.

I'm trying to decide where to mount the controller. I think I'd like to mount it in the furnace area since we rarely use the furnace (we're only warm weather campers). If we were to use the furnace, it would be at night when the controller would not be working hard. Our RV has duct work so there *shouldn't* be a buildup of heat in that area. Also, there appears to be lots of room for air flow.

Anyone have other suggestions?

The converter should be mounted as close as possible to the battery bank. The closer the better, but not in the same compartment. Also, the wire size matters, both between the panels and the controller and the controller and the batteries.
