awning questions help please

Don't know if this is helpful or not since I don't know what Coachman does or does not do in terms of customer service. Mine is built by Winnebago and when mine (fabric) needed replacement, I called Winn C/S, gave them my serial number and they shipped to me, the next day, all new awnings of the same fabric and color. I didn't need to measure anything in that they keep track of all the specs of each unit they build based on the vehicle serial number. I did, as a check, compare prices of similar awning material/size and found my mfr to be very competitive - to say nothing of the ease of doing business with them. FWIW
