Arizona Kaibab

Anybody out there familiar with Unit 12A East in the Arizona Kaibab? I could use any information you might have because I have to hunt from my vehicle since I am wheelchair bound. Are there plenty of roads? Do I need a 4 x 4 vehicle? What is the terrain like? What is the coverage like? I appreciate any help or advice you could send my way.

Thanks,
Roswellson
