Did a search here and found one post recommending Empire over Arxtic Cat ($400ish for a trailerable cover). Also found Carcovers ($250) and Neverland UTV cover on Amazon.

What is the experience or recommendation of the users here?

While trailerable would be nice, my main concern is coverage down in Mesquite NV, where it will spend winters under a carport, and will be subject to wind and moderate heat more than anything else.
