I am planning a move in a 10' u-haul from Monterey (central) CA, to MD at the end of March. I am not usually a truck driver and would like to avoid very curvy or possibly snowy mountain roads. I would like to make the trip in 7 days, and stopping for fun, esp. at national parks is a second priority. Would driving the extra miles to dip south on Route 40 save me from the mountainous driving on Routes 80, 50, or 70? Has anyone done this trip in a U-haul?
