You might be reading this because you received a warning while trying to make an edit to your trip and you clicked "Learn More" before proceeding - very wise! There are a couple of reasons you may be getting this alert.
RV-friendly
The RV-friendly features within routing options are exclusively available to Roadtrippers Premium members.
If you do not have an active Roadtrippers Premium subscription and try to edit a trip that had RV-friendly settings applied, the RV-friendly settings will be cleared if you proceed with making the edit. Note that if you have an active Roadtrippers Pro subscription, any preferential avoidances such as avoiding highways or dirt roads will be maintained as these settings are available for both Pro and Premium members. If you have a Roadtrippers Basic or a free account, then all routing options will be cleared.
In the "Heads up!" notice you received, you can select "Clear All" to proceed with the edit and remove your previous RV-friendly options. If you do not want to lose your previous routing options, select "Cancel" to cancel the edit you were trying to make.
Note that if you do select "Clear All" to make the edit and remove your previous routing options, this cannot be undone.
Unavailable Routing Options
Some routing options we used to support are no longer available. These include the avoidance options for car shuttle trains and tunnels, as well as the RV-friendly options for width and length.
If you open a trip that had any of these discontinued routing options set, you'll see an alert that states your selected options and route will update the next time you edit the trip.
Note that we do plan to bring these additional RV-friendly options back down the road!
