So we ended up camping our way south:
Moses lake county park, glacier apgar (2 nights), yellowstone madison (3 nights), jordanalle sp utah, kodachrome sp utah (2 nights), jacobs lake us forest cg, home. Wish we had another two weeks to enjoy the trip.
Post labor day trip had little to no haze, great weather squeezed between prior snows and the wet weather from the south.
Thanks all for the tips.
