Thanks for all the input. Regarding the last comment, I erred in explaining an important point - the troubleshooting and work is being done by a Mercedes dealer, not a Winnebago dealer. I apologize. I will check when I can about the differential being rebuilt or factory fresh. I am more worried than anything at this point, as I have not yet taken delivery of the unit.
I'm no mechanic, but I have a feeling with something like a differential that a rebuilt one is just as good as a brand new one. But I still wouldn't like it. I'd insist on OEM parts for a brand new vehicle like that.
