Hello! Brand new to the forum and I am posting this as I cannot find anything online to help with this dilemma.
I drive a 1965 Chevy C20 Truck and am trying to plan a trip. This truck does not like cruising over 65 mph and really prefers 55 MPH. I've taken it out on some of the Interstate Highways here in Texas and it is a terrifying experience to say the least. So the query I have is, does anybody know how to plan a trip based on the lowest speed limits? Ideal situation would be able to find 55 MPH roads to get from Austin to Dallas, for example. Thank you in advance for any replies that show up!
