Engine starting battery being charged while parked?

on the other hand...

"If" you have a 2006 Damon Daybreak...and it is as it was new...

the Converter/charger..and you leave it plugged in..the house batteries will over charge..boil them dry and render them scrap.

the chassis battery will not charge and with the slow drain..will discharge completely draining the battery and killing it also.

So plugging in once a month to maintain house battery and installing a knife switch on chassis battery has worked well.
