The OP's problem is the FL starting location. No matter how he cuts it, he has 3-4 days to get to the West which probably factored into the one trip plan. Growing up in the South East, our vacations were FL, TN, Ark, Carolinas. Dad wasn't crossing TX - period. Burned up too much of the vacation time. CA is a much better starting location.
I like one RV trip and then fly to SD for another trip. Or, drop CA/OR completely from this trip and make another trip where you hit more spots between San Diego and Crater Lake.
Crossing TX is the absolute pits. Crossing OK on I-40 is only slightly better (horrible road-where we had our flat tire).
If I were heading west from FL, I would drive to Natchez, pick up the Natchez Pkwy. to Nashville (the parkway is a destination in itself-really neat), then head west from there on I-70 or I-80, bypassing, TX and OK altogether.
If you aren't retired and can't be on the road for months, IMO, the only way to do the west coast from the east coast is to just bite the bullet and haul butt out there and back. That would be hard and boring for kids. Then once you're there, limit daily driving to an hour or two. With kids, I'd fly out there, rent a car, and maximize the time there sight seeing.
