I'd be tempted to buy it 'on spec' just to have around. And yes, I have seen an awning over the front window.
Go to the zip dee site and look around - http://zipdeeinc.com
If you go to services, you will find a wealth of information from parts lists to how to service your awning.
We had an extremely good experience with these folks late last summer. We had trashed the main awning due to being novices and stupid and leaving the awning up when a storm blew in while we weren't there..... familiar story I'm sure. Anyhow, we made a trip to the factory in the Chicago area for replacement. Well, they wouldn't replace the awning, said it could be fixed and not to waste money on a new one! How often do you hear that?! So with the money we saved on not replacing it, we added full window awnings on the traffic side, and the back, plus bought the sun shade for the main awning, plus a chunk of the stuff big enough to cover dog crates at shows.... and still had money left over! Oh, we also had the middle support arm put on the main awning..... plus they plugged us in to shore power, and water (no sewer hook up) for the night.
I've got a factory price list around here somewhere, who knows where. But the two single, most expensive items as I remember them are those great chairs, and the fabric by the yard! Everything else was so reasonable. And you can buy direct from the factory!
So, buy it if only on spec, and talk with the factory Monday. Linda there is so-oo nice!
