Anyone have good/bad experiences to share with enclosures. I am looking to buy upper and lower doors for my 2014 Rzr 1000XP. I’ve looked at enclosure on sidebyside.com but it says the doors (upper and lower) are Velcro attached to stock door? Seems like that would be problematic and not very durable. Polaris says on website that their doors "integrate" to existing stock door. Does anyone know what integrate means? Is that bolt to door? mechanically attach etc..???? If so, I’d think the Polaris doors are the way to go for durability standpoint?? Any help appreciated!!
