More power problems

I think I've already said that's the plan. Interstate isn't open on Sundays and I was following other users suggestions on what to check first. Fwiw, I've already had the batteries in for testing at interstate twice and the dealership checked them once. Since they were brand new when I bought the camper, warranty would be appropriate. However, I want to be sure that pushing for the replacement is not a waste of time. I tried to get them replaced last time I dropped them for testing but interstate changed their mind at the last minute.

I appreciate all the suggestions even if it's perceived that I'm ignoring them.
