I just saw your location, I lived in Havasu while stationed at 29 palms in the Marine Corps, I think these tires would do great around the type of terrain you will find in western Arizona.
Did'nt loose interest in the truck just been out of the country for a while, I plan on a flatbed, roof top tent, water system and a seperate 12V/110 electrical when I get back home this spring.
Man, that thing is awesome! I too was skeptical about the yellow, but it looks good. I'm torn on my next vehicle being an old Suburban, old truck or Land Criuser. I've got some time to figure it out, my Tacoma only has 60,000 on it.
Good looking truck!
