Thanks for your reply. I already have a 100w solar panel and controller that came with the rig, but it only charges the house battery. I was thinking of a Battery Isolation Manager which would connect both the house and chassis batteries while charging, and isolate them when not charging. I've not yet been the victim of parasitic loss, but don't understand why my sprinter does not have the same capability to disconnect the chassis battery as in other or previous models.
