well, previous topic dealt with my house batteries. turned out old ones were dead. replaced both, all was well. So day before heading out for Oregon i do some prep. began by retracting leveling jacks ...
All still a little confusing. Hooking up 2 batteries in parallel is pretty straight forward and "should" have nothing to do with your chassis battery that allows your engine to start. Unless you hooked up something very wrong and fried a lot of components.
