Summer is peak season for NP. Traffic can be a problem in popular parks. Can even be nightmarish at Yosemite NP.
Summer is also too hot for Death Valley & Joshua Tree. Also these 2 parks are best enjoyed by taking the trails instead of driving thru.
Some people have posted their detailed trip reports on West/Southwest NP on the Sina.com site. You may want to check them out for planning purpose as their starting points are San Francisco or LA.
