UPDATE: UnderBed Insulation
We are on an unplanned camping trip, boondocking for 10 days in Southern KY. We got down here on Friday, it went to 10* at night and the queen bed was like sleeping on a skating rink. Needless to sa...

I debated putting the Reflectix between the matress and plywood vs under the plywood....decided underneath would be better, would is pay to add another piece?
If you can live with a higher mattress, I believe that you would get more value for your dollar by putting foam under the mattress rather than Reflectix. Reflectix used like this (between two other surfaces) is only R1 (+ any reduction of convection....which can be eliminated with simple plastic sheeting). I think the main area to look at is where the bed is hinged as this would be difficult to seal from underneath.
Keep in mind that battery capacity is reduced at cold temps. At 10 degrees, your battery capacity is only about 75% of what it is at 77 degrees. Of course, during just a night or two, the battery internal temp won't get this low, but it will still be reduced somewhat. Regardless, I wouldn't advise trying to add the load of a heated mattress pad to your batteries unless doing so allows you to significantly reduce your furnace run time.
Keep warm,
