The last week of July will find me attempting to deliver a 14' u-haul load of "stuff" to San Diego in the fewest hours possible with 2 drivers. I see several options depending upon which mapping service you consult. Google sends you essentially I-90/I-15 via Butte, MT, Salt Lake City, and Las Vegas. Seems to be the long route but follows major Interstates. The other options appear to be the US-395 or 95 to I-15 routes. More direct on paper, but obviously 2 lane in many stretches and slow through towns and behind agricultural trucks/equipment. I am a very patient long distance driver with very quick bio/fuel stops and will carry a cooler. We plan to attempt this in roughly 24 driving hours (with appropriate rest breaks). Does anyone care to weigh in with any advise?
