I'd also suggest "camping in your driveway" if you can. You'd be amazed how many times you move stuff around because it just doesn't work the way you planned. (I've reorganized the inside cabinets twice in two trips out and DH has been moving the outside storage around too
Also, you might want to pack several gallon jugs of water for the furbabies. We've been warned that the water out west is saltier than what we're used to and we don't want anyone getting sick.
Personally, on the road, I like stopping overnight at the Cracker Barrel, but that might be because I enjoy the hash brown casserole so much
Enjoy your trip. We're planning Memphis to Seattle this fall and are keeping it to 400 miles a day - we get the best mileage at an RPM that works out to about 62 mph. So, that's about 7 hours of drive time, plus stops for the dogs and such. DH drives a big red truck for his day job, and I'm learning to drive the Erve, so we can take turns. (Or I can at least drive an hour or so and give him a break)
