Default Battery issues

Our new BT Crusier will not start after sitting a couple days. Installed a new battery and it still does it. We are not leaving anything turned on. Any idea what is causing this. Nothing in the coach runs off this battery, just the Ford.

Grab your multimeter and test the battery with the Coach off, should be in the 12.5V +. Then start the Coach and test the alternator with the accessories OFF in the coach, you should see voltage in the low to mid 14’s. Then test the batteries, the voltage should be very close. Next turn ON all the accessories, radio, blower, lights etc, the voltage should only drop a few tenths of a volt. You should still see high 13’s to low 14’s.
