Hi. I also like to journal our trips with maps. We use rv tripwizard. It allows you to save past trips and make notes. It also can be configured to height, weight, propane and maps route accordingly. Rvtripwizard.com.
One the route is established I use google maps or waze during the trip as it has audio alerts. I am hoping to install RV GPS soon also. We are 12’8” tall and 24,000 lbs so do not want to go the “wrong” way.
Good luck,
Carol
