Camping my way to IRG 2.0

Hey everybody!
I'm sitting here and thinking about my route to IRG from Albuquerque. Since I don't have a trailer yet I was hopeing to stay at motels along the way, then I realized how much it will cost me.
So being the cheapo that I am, I'm thinking of camping as I go. The only problem is I am don't know where to camp in Arizona or in CA and I don't know the fees either.
Does any one have any good suggestions on camp grounds along I-40 thru AZ and on the 1 in CA?
Thanks Mandy
