350-400 miles on long trips. On the road before 9 and off when I hit the limit. Remember time zones changes as you go west to east, losing an hour. Take a rest stop after 1.5 to 2 hours, works for us as our puppy likes to stretch her legs as well. Two useful tools I use is The Next Exit is great as it has mileage, rest stops and rv friendly fuel stops. Other tool I use is My Pilot is great as it gives distances off GPS, so gives mileage from current location to Pilot stops whether u use them or not. Safe travels to you, enjoy the ride getting there safe is half the fun.
