Moving from Miami to Seattle early September- first time driving cross-country

[Cualkiernombre]

Hello everyone, been browsing around this great site and could not find any thread of someone driving cross-country during early September. My wife and I will be driving from Miami to Seattle in our honda civic the first week of September, after labor day; we want to avoid the heavy traffic on the highways. The route that we have planned so far is passing thru Memphis, Albuquerque then Grand Canyon using I-40 then, head north to Salt Lake City then I-84, I-82 and I-90 to Seattle; driving for at least 10 hours everyday until we make up north, trying not to take longer than 5 nights on the road. Any suggestions and advice will be greatly appreciated. Thank you in advanced :)
