Have 2009 Roadtrek 210 and the chassis (Chevy-Express Van) battery continues to discharge to nothing within 2 weeks
while sitting at home and plugged into the house. This is the second battery to need replacing. I earlier installed a cut-off
switch, under the dash, to eliminate radio & any RV-coach link to that chassis battery, but it will still be dead in 2 weeks.
I Emailed Roadtrek...waiting for reply, but meanwhile what's the largest capacity battery I can install up front on this Van?
