Agree. I'm in NY with my first TT. I feel a lot better looking out the window at 12" snow fall and its snug under my new Adco cover from CW.
Just a level of comfort, for me.
It does tie down tight and we've had some intense winds with no sign of flapping.
My two cents. I have XLR27 and cover it every year but the first year we bought it. Live in New England and fall leaves and such can leave a mess and don't forget those black streaks.
One thing no one has mentioned is you need to cover all sharp edges. And your rain spouts, drill out a Tennis ball and add to each spout. I didn't the first year and had to patch quite a bit. The sharp areas like stairs just place foam padding under cover.
P.S. You'll need a good step ladder to. I find one on ethier side works best.
