I'm a new RV'er. I purchased a 2008 Tiffin Allegro Open Road, with a Ford Triton chassis. On the dashboard, there is a light in the form of a battery that flashes from time to time. It appears to happen when I'm on the highway, going through slightly rolling countryside along the interstate. As near as I can tell, it tends to happen only when on the down side. I've checked all the batteries and all connections are tight. The water levels are good in all batteries.
Any ideas?
