I had made a reply, but it apparently didn't make it to the forum. I would worry about the bubbles, since it indicates a delamination problem to me. That roof is pretty flimsy to begin with, so any further compromise would be very worrisome to me.
I am going to be pulling a trailer behind my 211S tomorrow. I am moving my Stained Glass studio into storage while I sell my house preparatory to moving back to San Antonio. I will let everyone know how it feels to pull about three thousand lbs behind!
