Honestly the Pioneer in stock form is pretty damn well equipped for Moab. Our first trip the machine was stock and we had no issues doing the major obstacles. I Would suggest a good skid plate that completely goes front to back and the sides. Our stock one took a beating and That was the first thing we upgraded. It seemed like we were always dragging the bottom so I ended up upgrading the a-arms to superatv forward arms front and rear so I could comfortably fit 30" bighorn 2.0s. We surprise a lot of Can-am and RZR Riders every time we go! As far as Moab itself, Get the Trails book by Wells. Its a very good tool if your alone. I Would join our facebook group and coordinate with someone whos already riding the area and tag along. We are in Moab pretty often on the weekends!
Moab UTV Group The Rentals/Hotels are expensive. If you like to Dry camp I can suggest a few spots for Campers, tent camping there's a lot more options. Just about any place in town has great food however we are cheap and try to make dinners/lunches as much as possible but sometimes your so tired from the sun, youd rather grab something. The restaurants are pretty crowded between 6-10pm!
