Those words "beautiful, peaceful, and healthy" say it all. It has kept me engaged to the mountain bike and the world it opens up for the past 36 years.
Yes, as Capt suggests, you can convert a 'normal' mtb rim to be used for tubeless set up. But get tubeless tires for sure. The sidewall is shaped differently, often different compounds are used to make it more pliable to grab on and conform to the rim better. I like the Bontrager tires because they have a compound that really 'sucks on' to the rim edge and seals well. Also, certain brands of tires are very finicky with certain brands of rims for this set up. Search 'reviews by bike shop mechanics' for these anomalies.
In case you missed my tutorial on setting my Midriff-ter tires up tubeless this year, here's the link:
I also highly recommend Orange Seal sealant! It has great elasticity for the hot / high / dry climates and the particles I mention in the video really do help seal larger holes and it's higher viscosity doesn't break down as fast as others.
I really like the feel and stance of the bike in this setting. A drive train side would have been the frosting on the cake, but it's still
really good! I cropped it and gave it some juice....
