Well I wanted a cheap solution to an awning for my 16' 86 casita
. I also didn't want to drill holes in the top because I wasn't sure my cheap awning idea would work.
It, however, worked remarkably well on its first trip. Went up and packed easily. I bought a plastic tarp from Lowes. I mounted a 10' piece of 3/4inch PVC pipe to one end with screws and washers. I drilled holes in the PVC and put the screws through the reinforced holes in the tarp using small fender washers. The tarp rolls up on the PVC and the PVC bends to conform to the curve of the Casita
top. I put 90 degree elbows on each end of the PVC and drilled a hole big enough for the spike at the end of a tent pole to fit through so the pole would go into the open end of the elbow and the spike would stick through the top.
I had a couple of old tent poles, stakes and rope to finish off the job.
The tarp is held in place on the Casita
by three pieces of 1 1/2 inch nylon webbing and bungee cords which attached to small eye screws I set into the aluminum molding that runs around the sides of the shell. It doesn't look tight or secure in my attempt at drawing the configuration but was, and traveled fine.
