My family will be moving from the SF area to Seattle and am trying to determine whether or not to drive up I-5 or 101 - especially since I will be doing the majority of the driving. While my car is in good shape and I am planning on getting a good tune-up before leaving (brakes have already been worked on), I am not too fond of steep grades - especially in an automatic. There is a chance that I may be renting an RV for the trip due to having an advanced cancer person along and do not know whether a car can or should be towed behind the RV to help economize on expenses.
I have gotten maps that show the elevations of the various roads and have been playing with Google Earth to get a better idea of what the roads are like but would really appreciate any information.
Thanks in advance,
