We got our first FW, 2011 Keystone Cougar. I have a bunch of questions: Going to try snow birding, Just too cold in northern Minnesota any more!!! What type of jack do you carry, or use TV jack? Ho...
Carry a multimeter to check your battery bank voltage; you don't want to dip much below 12.1V because the batteries can start to sulfate and lose charge holding capacity. If you have a 12V 'cigarette lighter' style outlet in the unit, you can get a voltage meter that plugs right in there instead of using multimeter leads on the battery terminals.
