We usually schedule about 350 miles or so a day. Normally this will give us about 7-8 hours of travel time a day. This includes a lunch and bathroom/gas stops along the way. I usually travel about 60 mph. When you cover the distance over time devoted to travel, we are averaging about 50 miles per hour. If we have to navigate two lane highways or major city Interstates, we usually are traveling a little less distance per day.
When we plan a multi-day drive, I'll plan each overnight destination including where we will stay overnight. It's a lot less stressful having a travel goal each day with a guaranteed campsite.
