Finding camping in the parks will be very, very difficult. Some parks are full months in advance. They may have a first-come, first-serve area but you will ABSOLUTELY need to be there at 8am. If you sleep in the car, you will get a hefty fine. Plan ahead. Even camping outside the park in a private campground will be difficult to find and frequently fully booked. Realize that "outside" the park can be more than two hour's drive easy. Can really put a dent in your in-park time. Get a National Parks of the West book. Super, super helpful. Will outline all the campsites and outside park camping and hotel/hostel options and everything you need to know like hours, etc. I used Fodor's but they're all probably pretty similar.

I've been to all the national parks. Yes, all of them. Have fun!

I go to Moab every year in my stock Toyota FJ. I would recommend getting this book for your journey. It gives tons of info on all of the trails (turn-by-turn directions), and tells you how difficult they are. I would stick to the easy trails in your Bronco, I've found that "intermediate" in Moab is pretty hardcore. There are plenty of easy trails out there that will still get your heart racing and provide ridiculous views. Two of my favorites are Gemini Bridges and Long Canyon. I'll be there next weekend!

You're going to want an America the Beautiful Pass. $80 for unlimited national park admissions for one car for one year. Most parks are around $20. I also recommend getting one of the National Parks of the West guidebooks so you can link them all together and what-not. I've been to all the parks in a previous version of this book http://www.amazon.com/Fodors-Complete-National-Full-color-Travel/dp/0307928462/ref=dp_ob_image_bk

Linking national parks is the classic, American way to road trip. Enjoy yourself. I've been all over the world but my favorite trip was spending a few months living in my pickup in the parks.

Pretty sure it's just a standard forest service road.

But
These books are great for trails.
Pretty much the bible.

There is one for Ca too but it's not as good.

I recommend these:

It depends upon how much time you have, but don't limit yourself to national parks.
