Wow. You are living a dream. Northern Arizona is beautiful. I used to go up north every chance I had when I lived in Phoenix.
There is nothing like this in the Carolinas. There is no wilderness BLM lands around here and nowhere to camp without staying in an expensive campground with screaming kids and barking dogs.
You'll love Arizona. Stars are amazing at night, get a telescope if you like stargazing.
You'll have fun working Japan from there. Europe is much harder to work from there but a good antenna and a kilowatt will help.
You know, it's amazing what a can hear if you park somewhere in the mountains, away from civilization.
Good luck to you buddy! I'd love to hear more about your endeavors.
BTW, we have been looking for a travel trailer similar to yours. I'll be pulling it with my 2016 4 Runner or my 98 I-6 Grand Cherokee.
How do you like your trailer so far? Any issues pulling it with your v6 (I assume) truck?
