2015 Thor ACE - truck battery dying

[LB27]

I've recently purchased a 2015 Thor ACE and have had the battery in the truck lose it's charge several times over. I tested the battery and it is good, I can recharge it and as long as I fire up the rig every week it seems to be fine, so I believe there is a slow drain.

I'm fairly confident the electrical drain is coming from the standard dash radio is always on (the light leads me to believe this). I cannot figure out how to turn this off... Seems like a silly problem but I'm not sure what to do.

DOES ANYONE KNOW HOW TO TURN OFF THE TRUCK RADIO FACEPLATE?...

Thanks for your help!

Have you actually had it load tested?
Any auto parts store should be able to do that for you.
Good luck!

Press and hold the power/volume button.

If the battery is several years old the drop in voltage is typical
