Here's another awning:  I have a Sidewinder II by Carefree of Colorado.
I bought it at a local RV shop; it is made 10 miles away in
Broomfield.  I have seen 2-3 others on Vanagons in the area.

I bought the 10' length; there is also an 8'.  The awning rolls out
to 8'.  They have a special mounting bracket for Vanagons (plus a
generic van bracket) and it is designed to hold the awning and
clear a Westy poptop.  The brackets clamp to the rain gutter.

They say the 10' requires two people to set up, but I can do it alone.
I like the 10' because it really shades a lot of the Vanagon plus
can hold the picnic table that we usually drag to be under it.

I've had it 2-3 years and really like it.  The cross-section shape of
the awning "box" (aluminum ) is not round like others but is
rectangular.
