Well, it certainly took me long enough to find this problem, especially with all the topics about batteries, but take a minute to check the size of the cables connecting your second battery to the first. I was checking the water in the batteries before our next trip and noticed that the cable from the first battery to the rig was 6 guage, but the cable the dealer used to connect the second battery was 12 guage.

That's ok when you're not drawing much current, but it unbalances the batteries when you're opening or closing slides or charging at a fairly high rate. I don't think it will cause a problem in the short term, but the general principle should be to use the same size cable for both batteries.
