Need advice to be prepared on the trail

So, I have been reading a lot of posts here on many topics concerning the 900 EPS Trails and I am looking for advice to make sure I am safe on the trail. Since I will do most of my riding as an only vehicle I want to make sure I have as much stuff on the machine that I will need to get out of sticky situation.

So far I have come up with the addition of the following items:

Fire Extinguisher, found a good one at Rocky Mtn ATV

Spare Tire and Carrier (I really need help sourcing the spare tire carrier, one that will work with my Polaris Cooler in place and also I need a good all around tire, I have read on here that the stock tires are not that good)

Desert Modeling Concepts R2C filter

Lower door inserts (not so much for safety, but to keep cleaner)

I already have a half windshield, winch and roof. Is there anything else you guys think I should have with me, other than food, water, gps, warm clothes, first aid, fire starter.

Thanks in advance.
