Badlands National Park in western South Dakota. That place is spectacular. Looks like the surface of an alien planet. Thankful I lived to see it. I also enjoyed Wall Drug yesterday, and for breakfast this morning. Good coffee. And it was 5 cents. For real.

Also visited the Minuteman Missile Site. Was interesting to me, since I lived through that era as a kid.

But I discovered today that my RV battery that powers my fridge, microwave and A/C is dead. No clue why.

Have to take care of that first tomorrow. At least I am now in the vicinity of Mount Rushmore. Only took me 7 weeks to get here, lol.

You should have three ways to charge the house battery.

1. Solar
2. Converter when plugged into shore power
3. Truck from accessory 12v on 7 pin.

If you were parked for a while (I know you said you were in a hotel) with the 12v fridge on and the trailer was in the shade, or just up north in the winter with some cloudy days your solar may not have been able to keep up. I think a lot of people end up adding another panel.

Do you have a lead deep cycle, or a LFP battery? I think they are still putting normal deep cycle on by default, which is fine with a three way fridge but could be marginal with a 12v. If you decide to swap to a lithium iron phosphate you may want to get a heated battery if you keep it on the tongue, or move it to your pass through. If you swap take a look at Redodo, we have a pair on the boat going on 5 years now that are doing really well. Added a third just for electronics about 1.5 years ago.
