Thanks everyone, RDS in flordia seems to be the only one with one under 12" H. I'll try to contact them on monday.
You ask about backup lights. I have install my lights at the front legs. I know most people think that the lights need to be at the back of the coach. I wondered why, that is the part of the coach I can not see from the driver seat even in day light. I like to see where the wheels of the coach are going. Therefore, with the lights at the front legs, the total area around the wheels and to the sides is visible from the drivers seat. Also makes connecting utility and blocking the wheel easy in the dark since the total ground area cast in light.
