Wonder if anyone has done it in less than 5 days and experience related to it.
When I was relocating cars for folk who had moved from coast to coast, we were always given 10 days for the trip. The company's professional drivers had to do it in five days - for safety's and by law.

For an amatuer who does not regularly do this run, it would be a gruelling trip, especially in the short daylight hours of winter. Anyone who tried it, may no longer be here to tell of their experiences.

Allow the time required, even if that ends up being more than a week. Put safety before schedule, take note of all the above advice, and make it as enjoyable a trip as moving trip like this can be.
