I am really happy with them...  I've had them on trails, mud, and this past weekend the red rock of sedona.  They perform very well in all terrain I've had them on, oh and they feel like you have power steering on pavement.  I currently run them around 12psi.

Watch ebay I've seen some there, I actually found mine looking under rhino and asked seller if they had some that fit the Cat.  $225 for my set of 14"

The only reason to build a 50" unit is to pass the cattle gates in Utah on the GWT or Paiute Trails.  I've riden both and one trip from Salina, UT to Lake Havasu, AZ on quads.  Being on a 800 Sportsman seemed to just squeeze through those cattle gates on the trails.

But I agree I like the width of my Cat also.

Nice.... I really like the seats, and the speakers.  Where can I find a pair of those?

Nice Cat!  Are you a year rounder?  I'll have to make the trip down there this winter, check out some of the area.

I've had a few different gps units, both garmin and magellan.  The one I use now on the cat and in the car is the Magellan Crossover has color touch screen, comes with both topo and street maps, and a dust cover for the trail.  Also has voice directions on street maps.

I've helped my buddy change two belts on his rzr out in the dunes.  Now I haven't changed one on the prowler yet.
