Am moving from bay area to Dallas in july. Instead of shipping van, plan to drive from Bay area to Dallas
I already went through the map wizard on this page and prepared the plan. But want to run it with Gurus on this site so as not to miss.
Plan is start on july 1st and want to by reach july 4th evening(total of ~4 full days)

1. On first day take hwy 5 and then 40 and visit Red rock canyon, Mojave, Go through hwy 66 for some distance and get onto hwy 40 to reach Grand canyon, south entrance and stay for the night
2. Day 2, (go for sunrise from south entrance early in the morning and back home to relax) - planning to drive 6-8hrs only. will be starting late and visit walnut canyon, meteor crater, petrified forest . Anything else? Please suggest place to stay. Also any good camping site?
3. Day 3, if nothing important is there to see, drive and reach dallas by evening.

Am a big fan of national parks and already have Grand canyon in my list. am regular visitor to Sierra's so don't want to add to the list. Could you please suggest any other national park, not-to-miss places which can make the trip more enjoyable.

one of my friend might come with me but high probability of me driving alone.
Ohh forgot, I like stargazing and prefer to camp if possible.
