Congrats on drawing. When you say we, who are "we?" How many tags are you trying to fill? Are you hunting with family? Friends? I'm assuming that you're coming in from out of state, where do you hail from? Please pardon all of my questions, I'm just curious to know a little more about you, and what you're looking for from the hunt.
As far as maps and scouting go, make sure to contact the Kaibab National Forest, and have them send you a copy of their Motor Vehicle Use Map (MVUM). It's free for the asking, and you will want one with you. It shows all of the roads/trails that are legal to drive, and what you can take on them-- e.g. under/over 50". If it's not on the current MVUM, it's not legal to drive, no matter what it looks like or the other guys out there happen to be doing. The MVUM also delineates areas where your vehicle cannot leave the road for any reason-- not even to park to hike off to hunt-- you are limited to just passing through in your vehicle. These areas are not marked on the ground or any other maps, they are only on the MVUM.
I'm not sure what you're bringing as far as a camp set up, but keep in mind that on the Kaibab you are only allowed to park up to 30 feet from the edge of a road, so if you're hauling a camp trailer, and want to stay legal, you'll be camping right next to a road. I'm not sure how strictly the NF guys are enforcing this. AZGFD officers, by policy, will not enforce travel management rules, but the forest service guys might ticket you.
While the MVUM is useful for the road system, that's really all that it is good for. If you like paper maps, get one of the actual forest service maps. Those ones show more than just the roads-- mountains, canyons, streams, tanks etc. I suggest the Prescott National Forest map, as it shows the entire unit, with the exception of a sliver up by I40 east of Williams.
When you start looking at the maps, you'll see that access is, well, a bit too good. There are roads everywhere, so depending on your style of hunting that can be a good or bad thing.
For weather, bring your rain gear. It might not rain at all, but monsoons can linger well into September. A gully washer at that time of year is still possible.
Congrats again on the tags. I hope you all have a great hunt, and go home with the AZ bulls that you've been dreaming of.
