When we had our Zinger, we used camping world of Colfax in Greensboro got our warranty work. They were very slow (weekly calls usually did the trick) but honest.
country roads in Lexington NC got my old zinger in quickly for an awning repair. The plan was to leave it and pick up later. We showed up 30 min before closing. They took a quick look at it, said they could do it then and there so we waited. The repair was done in 45 min, they stayed late to finish it. They charged me less than $100 too.
Bill plemmons in Raleigh has been great to deal with for my sabre and it's many issues. I'm not sure if plemmons or country roads are approved for crossroads warranty or not but it is worth looking into.
