Depending on what part of Colorado we are going to or coming from. We will either take I80 or I70. Most times, it's I70. The one time coming home on I70 in Kansas. Got the bright idea of not going on the toll section of I70 on the eastern side of Kansas. So we let Garmin re route the trip. Spent 3 days taking a round about way around the toll road.
All of that to save a few bucks. Spent more on fuel then tolls in the motorhome.
