Hello. I have a 1996 Monaco Dynasty. In previous post I wrote that I had seen three states to Florida by tow truck. The same problem occurs which is the 4D batteries lose power after 2 days. I can ...
A clamp-on ammeter will tell where the power is going out and if any is going in. Unfortunately many mechanics are not well trained in electricity. 2x 8D is a lot of power to be drained in two days. s/b easy find.

If you had towed to the west coast I would offer to look at it. Best of luck at the next shop.
