What’s the smartest way to upgrade a Mule Pro?

I mainly use my UTV for outdoor trips and hunting weekends, and comfort plays a huge role when I’m out for hours. I’ve been checking out different Kawasaki Mule Pro accessories but I’m not sure which ones actually add the most comfort for long rides.

Do roofs and windshields really make a big difference when riding in unpredictable weather? Has anyone here added cab heaters or fans, and do they actually hold up in extreme conditions? What about seat upgrades—are they worth the investment for passengers, or is stock good enough?

Another area I’m debating is storage. Do overhead racks feel practical, or do you lose too much headroom? Are coolers or lockable boxes the better choice for multi-day trips? I’ve also thought about adding gun racks—are bed-mounted racks better than interior ones?

I’ve come across StartKnightMT in different UTV forums, and people seem to trust their accessories. Do you all think they’re best for rugged upgrades, or are they better for everyday add-ons? Out of everything, which accessory gave you the biggest comfort boost on your Mule Pro?
