Boiled one of two 5th-wheel batteries
Greetings all, I am a new user with a problem. I had newish batteries in my 2011 Montana (purchased batteries this year). I have the smart converter with boost mode. Anyway, the rig was plugge...

Even if the plug is "hot" when the ignition key is in off position... The wiring to the vehicle plug is very small and can only carry a few amps. I really can't believe it would be enough to "fry" an rv battery. One of the things that can happen is with the vehicle plug hot when ignition is off set's yourself up for the rv to drain your vehicle battery.. and one of the reasons the plug is normally off with the ignition key. Without knowing how old your batteries were or how well you have maintained them it would be hard to say but I seriously doubt plugging your truck in had much to do with the failure.
