Let me know what you guys think of this travel plan

I hope you have reservations at a campground already.

More and more "rest areas" are posted for no overnight parking.....and the ones that allow it, typically in spaces for big trucks, tend to fill up pretty early in the evening.

If you have a space reserved at the far end and have some flexibility in your intermediate stopping points, you should be fine.

I can run my heat without AC power but need to recharge the batteries the next day, either by driving or by running the gen.
