Has anyone come up with for good DIY functional and inexpensive awning.  I
have been looking for a used awning in the Denver area and have given up and
starting thinking of making my own.

So with awnings on my brain, I saw a truck go by with what looked like an
awning on the side.  Then I realized it was 3" grey plastic conduit.  That
got me thinking could you make a permanent awning with that tube, a tarp or
awning material, a pole to roll it up on and a couple of end caps to hold
the roll in the center of the tube.   Has anyone come up with something like
this, or something better?   I have been using a tarp, a couple bungies and
a couple extendable tent poles but it isn't quite good enough.
