U-Tube exaggerated.
I went to Polaris and built one. It was only $59k not 60k.
By the time your done, the Jeep still has more features, like AC, Defrost, comfort, the ability to drive all highways, more options, way more power, stronger parts....
The Polaris advantage is, I can go faster on the trails. (This is in their short videos on their site.)
If I was going to put an RTT on one of these it would be a modern hard shell. Lower profile, less likely to snag a tree branch while your zipping through the forest. My opinion, one of their marketing guys is blindly trying to grab a piece of the "Overlanding" Fad.
At work, quite a few people own side by sides. Their not too bad once you upgrade some of the weak components. They all have at least 10k in upgrades. This brings the cost of a fairly nice one close to $38k.
Take the almost 60k one in the video and upgrade the steering and suspension. Now your closer to $70k
