Besides the Polaris Factory enclosure, who else makes and sells them? I’m interested in purchasing a Polaris RZR XP 4 1000 soft cab enclosure. However, I’m not willing to spend the amount the factory is asking for one. I’m certain they’re of high quality, but my budget is currently quite limited. I searched both Rocky Mountain and SuperATV, but unfortunately, I didn’t find any available options.Thanks in advance for your assistance.
