How to keep Chassis batteries from dying w/genset on

Hi all:
I have a 2005 Mandalay 40E and have had many issues of going for a 2 day/2 night tailgating trip with generator running only to have my chassis batteries dead at the end of the trip. Looking at turning chassis batteries to disconnect, I see that my generator appears to be powered by the chassis batteries because if I disconnect that, the genset turns off. So, would an Xantrac echo charger or some type of trickle charge stop the drain on the chassis for a couple of days? Trying to figure this out and I am NOT handy. Thanks all.

  • Isn't your generator hooked up to the power (shore) power? Your converter should keep your batteries fully charged. At least that is how it worked with my Toyota class C that I recently sold.
  • Sounds like something may be broken. My genset charges both battery banks, it doesn't kill them.
