Here's another thought for you - Why not just use motels until you get below the frost line ?
No propane usage, no setup and takedown on cold short days. Make a motel reservation and I would think you might be able to drive a little longer instead of having to stop early to do setup. Warm bed at night and a nice long hot shower in the morning. Then just get in the truck in the morning and drive.
Just drain your water system or do the anti-freeze thing now and you'll be ready to leave in Dec.
