Zip Dee Awnings
When I had the Zip Dee awnings installed on my Overlander two years ago, Ace Fogdall RV in Cedar Falls, Iowa handled both the ordering and installation (Ace Fogdall is Iowa's Airstream dealer and is VERY Vintage Friendly). I was present when the Ace Fogdall technician performed the measurements, and it was a precision task that took the better part of 45 minutes for the three awnings - - the factory was contacted several times to verify that the necessary measurements were being taken. The installation was and is perfect - - and I am totally satisfied with both the awnings and instalation.
