Well thought out intinerary and plan suggestions for the trip out west. Every thing being relative, driving 8 hrs. per day is doable but can be tiring and stressful. Personally, I like to drive approx. 5 hrs. per day and stopping at every rest stop along the way. I agree about making reservations, I would look at a map and figure out what city or town I would be in after approx. 8 hrs. and then make reservations accordingly. Reservations gives you a plan to deviate from rather than getting into a town/city/area dead tired and then start looking for an RV park. While I don't personally use KOA campgrounds because of their high prices, KOA's are kid friendly and generally have pools, game rooms etc etc for kids to play and unwind. KOA's can be found in every state.
Another alternative consideration if practical, would be to rent an RV on the west coast and then just fly out allowing you many more days to really visit and enjoy your visit and sight see.
