Uncsheduled stop at Camping World in Hamburg, NY

I remembered that there was a Camping World location near Buffalo, and this morning, I looked it up, and we found it on the way into Buffalo- 

Our problem is we have no turn signals on the tow car-  Cummins Cincinnati diagnosed it as perhaps a bad umbilical cord, which we knew to be Camping World issue-  and this was the closest one to Cincinnati-  Well of course we found a nice new cord, hooked it up, and still no lights-  fortunately, they say they can take it in to look at it "within a half hour or so" and see if they can get it up and running- they suspect a fuse or a diode. 

It's now a quarter to 10 and we've been here about 20 minutes-  hopefully they can get us on the road soon, and I can get most of what I had planned done for today done.
