Spray painted an aluminum awning rail black. Had a local canvas company make 4 awnings. 2 are just for the windows. In the rain or a quick overnight stop.
I use bungee chords to the fenders so they stay in place.
In addition to the window awnings I had them make me a 5 x 5(driver side) and a 4 x 5(passenger side). The side door is too tall to have extended the awning over it.
And added a grab handle to the side door.
When the walls were off I added wood blocking/framing to all the areas I was going to attach something: windows, grab handle, power and blank inlets and awning rails. Also the trick was to carefully mark where the trailer wiring came down as to not screw into that!
