As stated before, on long trips, i would like to have the option to cover it. If the weather is good, you're right, no real benefit to covering it. If i'm traveling long distances and the weather is rainy/snowy, it would be nice for me to 1) protect the sled and 2) not have all frozen controls when i get to my destination and want to pull it off and ride. Also, during the winter months, my sled pretty much spends most of it's time on my ToyUp deck locked with the super clamp. With the time it spends up there, having it protected from the sun would be nice since i dont always put it back in my enclosed if i know i'm going riding again soon.
Are those enough reasons to just answer my post instead of questioning why i want a cover?
