Sooo, I did it and everything Gene said was true...lugging the cover up the ladder was a near death experience, it was very heavy and hard to manage. Un rolling and unfolding it and then tripping over the vents 14 feet up could've been a fatal fall....but alas its on. I padded sharp edges and then snugged & tugged....its still kinda a roomy fit and I may try cinch down some extra material up front.
I'm hopping but not overly confident that this will be good as I depart for three years....
I'll try and post a pic from the computer later....
