All this talk about mounting Solar
Panels to the top of fiberglass trailer including "blowing off" reminds me one reason I prefer portable solar. I bought a solar panel
10 years ago and bought some aluminum angle and flat pieces made a stand and it works great for me.
One things I ran across in Big Bend TX. There's a brush row in the campground on one side is nice campsites with lawn and shade, on the other side are campsites with full sun along with dust and dirt. A couple came in with a Scamp
with solar mounted on top and went to the sunny side because they felt they needed the solar in the sun.
Because I have such a small power usage chasing the sun every 4 or 5 days is just a lot nicer in my mind.
