I think your daily budget is a bit optimistic. You should allow $25 per night for RV sites and your food and activities budget is going to be tough to stick to, you are going to want to eat out and have a treat now and again. It also doesn't allow for the occasional Hotel etc, although I don't see the point in that if you have your room in the RV already paid for. Fuel prices are hard to predict but at $3 per gallon, fifty bucks should average you out at 150 miles per day so you may have a bit of change there.
For your routing, well you are missing out on some amazing National parks in southern Utah, Zion, Bryce canyon, Capital Reef, Arches and Canyonlands. The latter two are near Moab from where you could head to Yellowstone using 191 past Flaming Gorge Res and through the Grand Tetons. Near Seattle is Olympic NP and Mt Rainier and as you head further south past Crater Lake you could look at staying inland but going through Lassen Nat Volcanic park to Lake Tahoe and on to Yosemite, or you could head over to the coast for the Redwoods National and State parks.
You will find thousands of options as you continue with your research and you will find the annual National parks pass a budget friendly option at just $80 for entry to all parks, but that does not include camping fees. If you start in Canada I would recommend you head to Cali and do Yellowstone towards the end of your trip as summer comes late. Also note that if you reached Yosemite before mid May to Mid June the Tioga Pass [CA120] over the high ground might still be closed due to winter snow accumulation.
