My wife, dog & cat and I are moving to California in a few weeks and I have been debating which route to take. We have movers moving the bulk of the load but will be hauling a small U-Haul trailer with our V6 Honda accord (which is rated to pull 1000lbs). My main concern is going through the mountains on I-70 west with the trailer, although it is rated to pull it I don’t want to put too much stress on the transmission. If I take I-25 south to I-40 west I will avoid the mountain passes, however I am concerned about the heat. Any suggestions would be greatly appreciated. Thanks!!
