FW28z and HarryT thanks for your replies...
Here's what we have found out (confirmed by Thor by phone)...
Thor does not install a battery isolator in any of their Thor RV's that specifically have a Sprinter chassis.

We had been puzzled because our coach batteries seemed to charge when we drove but emptied quickly. The battery monitor lights would go up to full when we finally arrived at our destination; however, 15 mins of having a light on, the chassis battery monitor would quickly go down to 1/3.. and then 30 mins later to empty.

Bottom line: Thor told us MBZ doesn't allow Thor to put the isolator between Sprinter and chassis batteries for helping to "trickle" charge the coach batteries, instead you need to drive with your generator on if you really want a fully charged coach battery when you arrive at your destination.

HarryT..our Thor is a Citation 24SR. I would be curious if Thor tells you that you "do" have a battery isolator between your Sprinter and coach batteries, thus allow your coach batteries to charge while you drive without your generator running. Can you let us know what you find out?
Thanks again--
