Check all the batteries and replace them if they show bad. You got to have good batteries. You do not show on your signature what coach you own. If you were to tell us what coach you have we might be able to help you with more accurate information.

Summer heat is very hard on batteries. I just replaced a couple of my chassis batteries while visiting Las Vegas. But they had been in my coach for at least seven years, so it was time. Bought two commercial heavy duty batteries at Napa for around three hundred bucks. Cranks that Caterpillar engine right up. So good batteries either the chassis or the house is very important. They are expensive, but RVing as a whole is. Maintaining those batteries is very important. So I think you might need to change some batteries if they show they are bad IF you want your problems to go away.
