Best Accessories for Kawasaki Mule - Where to buy?

I recently got a Kawasaki Mule and am looking to customize it for both work and recreation. I’m curious about the best accessories you’d recommend for improving functionality and comfort.

So far, I’m considering a roof, a windshield, and maybe some storage upgrades. For those who use their Mule in rugged conditions, do you have any suggestions for skid plates or protective gear? Although, I know about StarKnightMT store to buy kawasaki mule accessories but would love to hear more suggestions from you guys.

Also, has anyone installed gun racks, under-seat storage, or sound systems? I’d love to hear what worked well for you. Any tips on brands, installation challenges, or where to get the best deals?
