Similar to a carport. Cost was just over $1K. Not only does it keep it out of the hot sun, it keeps it dry.
Excellent idea, AND the shelter provides a place to mount way more solar panels than will fit on the trailer roof, if you orient it properly so that one side of the roof has maximum winter sun exposure (since you get less sunlight in winter, optimize the solar panel system for winter, and you'll still be fine for summer).
