I have a SE and I can attest that the material is up to the job. It's the material semis use (the trucks that have 'curtains' along the sides).
After I pick up my Cobra from Sacramento, the top might come off. I don't plan on trailering any farther than a hundred or so miles to any 'local' track. Plus I'm not preserving any shiney finish.
And, it looks better than a closed trailer.
Oh, and Featherlite makes a really nice trailer. Great brakes, too.
