Two feet saves on cost. In any case I probably would want to come up short of 4 ft because although the panel is 4 ft long the slope in reduces the actual length. I think 3 ft might be easier to build.
I moved the spare over on the back of the trailer this morning. This gives me room to U Bolt a little giant ladder to the right rear of the trailer. I can use both for attachment points to brace the boat tail.
