Welcome to the RTA Forum!

I-80 connects Chicago to Sacramento, so that's the pretty obvious route choice. There really aren't many other options if you are just looking to get there quickly. It's a 2000 mile trip, so 4 days is about right - putting you on the road for around 9 hours each day, assuming things go well.

Of course, by mid-november you will have to keep an eye on the forecasts, and it's possible a winter storm could slow you down, so having an extra day available just in case would be a good thing.
