Has anyone made their own awning for their camper? We just bought a 2000 Starcraft Venture. It has the track for an awning - but no awning. I checked out the prices of an add-on awning and it about took my breath away. Can they be that hard to make? I saw that a guy on e-bay sells a pattern/plan for making your own awning. Just curious if anyone here's done one themselves? Thanks.
