Well at least you spent your money on a good machine. Now, about your questions. The winch thing, stay with the regular bumper mount and go with a WARN 2500. You WILL need the extra power some day and be thankful you had it. GPS problem?? Unless you are planning to go off trails, WHY?? As far as the gear box, get one that wraps around so your passenger can have comfortable ride and you can put alot of crap in one. I have more room in mine then you can imagine. RADIO??? are you nuts?? BEER, save it for after the ride unless you absolutely need one. If that is the case, pack it in tight in the gear box like I do. It will be shaken up but hey, use the spray to clean off your face. Valves?? NO IDEA Shock covers?? If you spent all your money on the machine then you dont have enough for these or any of the other things you listed. BUT if you have the extra money someday I would buy them. I have not as of yet and have not had any problems but who knows Good luck and have fun riding
