Well I can certainly entertain the idea of producing other colors. Sure. It really comes down to cost and what the manufacturer can or is willing to accommodate. So the two colors I was thinking to fit most types of hybrids is Dark Brown and Black.
As for the comment about the heat, This awning provides shade and an air gap for cooling of the inside bunk. On a hot sunny day, these awnings will provide excellent airflow to keep the bunk and the air inside cool. They also provide much needed shade for the interior (about 70% of the bunks' surface area is shaded with the awning) to even reduce the need for reflectix in the windows as well. Plus it looks good and you can open your windows in the rain!!!! (the reflectix and solar blankets cant do that)
If everything goes well in the meeting, I can hone in on a production cost and First Run test fit, then I will have pricing. I will probably start a group-buy to get the best prices for you and to expedite the process of getting these. Everything is better in numbers.
I will still need to find a powdercoater and welding shop for the brackets and such. I assume White hardware or Black hardware will be the colors people will want, so those will be the choices.
