Speaking from experience, PVC pipe is an absolutely TERRIBLE material to be using for framing. I tried building a carport from it once.

It is flexible, so it will twist and sway and flap all over the place in any wind, such as the 60mph buffeting that you will give it.

PVC does not have good fatigue strength, and when it fails, it fails catastrophically. After it has been twisting and swaying in the wind for several hours, it will crack and then shatter, sending panels flying into the wind, and possibly causing a severe accident behind you.

You are spending more money building this trailer than you can possibly save on improved gas mileage from it, even if it miraculously doesn't break.
