Hi Reol,
It'll depends on the what the park basically tells you how to put the trailer.
One park was a powered grass site,and the one pictured($125 a night) was a powered one with shadecloth on the ground.We swung the trailer 90 degrees from how it should be and had the trailer and softfloor section on the shadecloth.The park stated that you could only put a grass mat/shadecloth on the grass,no tarps etc.So we believe we had to swing the trailer as is, it created a perfect view.
Also we had to contain our vehicle on the site provided so this was the only way to set up and contain everthing.
