I have an enclosed trailer.........
If I haul the SS on my open trailer, I would cover it......
I don't like road grime in every nook and cranny.......
So cover it this way........
Get light weight soft blankets and cover the SS.
Then put your trailering cover over it.
You'll never get a dull scuff anywhere.
I was a snowmobiler for 35 years.
I've seen machines that the flapping cover broke up the decals on the shroud, and dulled the windshields badly.
I always covered my sleds this way, and never had a "dull moment!"
Polaris started making a precover that fit over the shroud. I bought one for my wife's sled and it worked flawlessly for years!!
My buddies wife sewed an entire cover out of terrycloth which was awesome!!
