I purchased the RZR for farm use, hunting and trail riding. This is what I designed and built for mine to haul my 2 cow dogs & just about anything else. I designed it to hold 2 large soft sided foldable dog cages. The dogs load from the front seats into the cages. There is room under the rack to carry spare tire, jack, tools etc....
Even though I went to all the trouble to give him a place to ride. Ranger still perfers the shot gun spot.
