Salt Lake City...KOA downtown. Free shuttle to the Square. Plan on at least a day there. We saw the Mormon Tabernacle Choir perform on live TV. Ask at check in for their schedule.
Arches/Moab...Portal RV...stay in the 'owners' section. Slightly more per night but pool/spa etc is worth the extra. Visit Canyonlands and Arches from there. IMHO, the Arches rival the Grand Canyon in beauty.
Grand Canyon...Trailer Village inside the Park. Free shuttles from the campground to all the attractions on the South Rim. If you stay in Williams, the train ride is a waste and you'll be on their schedule instead of your own. Watch for elk inside the campground and protect your sewer hose as the Ravens will peck holes in the stinky slinky.
Hoover Dam...only access is now from the Nevada side. Several casinos will let you park in their lot. Check with security to see if they charge. Worth the visit..take the tour, you won't be disappointed. Several campgrounds in Boulder City that take Passport America.
Las Vegas...the Oasis is the nicest park but expensive. Stay off the strip and prices drop. Sam's Town has a reasonable rate as does the Thousand Trails.
San Diego...several choices...Silver Strand has some beachy areas, but Mission Bay is the best.
Anaheim...ugh! not too many choices because of Disneyland. All expensive. Orangeland RV Park is nice but expensive. Anaheim RV Park, I believe is closed. If you don't mind driving a bit, try Canyon RV Park in Yorba Linda. It's about a 30 minute drive to Disneyland. If not going to Disneyland, I'd check out Dana Point State Park and camp on the SAND. Nice location and lots of restaurants in the marina.
Santa Barbara...the State Parks are the best along the coastal region. Carpintera has full hookups. Refugio Beach is right on the sand. Ventura County has sites that overlook the ocean but are right on the highway.
Monterey...is pricey and camping is at a premium. The fairgrounds is a disgrace. The pier area for dining is very nice. Try Bubba Gump's. If you're looking for a real gem of a campground, try Mount Madonna County Park on Heckler Hwy about 1/2 way between Watsonville, (artichoke capital of the world) and Gilroy, (Garlic capital of the world) Heckler Pass Hwy is also known as California 152.
Traveling north, I would take Hwy 1 and follow it up the coast along the seashore. Beautiful drive and you shouldn't have any problems with your rig. Larger rigs are not advised. Check out all the lighthouses along that area. Further north, be sure to visit the Giant Redwoods. There are many State Parks along that area that are beautiful. Make sure you travel the Avenue of the Giants and do some short hikes among the redwoods.....Dennis
