On their website and in their app you can request displaying only Pilot/Flying J that have RV fuel lanes and RV Parking. A new Pilot was built E of Tucson, best one we have ever been to for the RV lanes. We found another new Pilot up near Carlsbad NM that also had great RV islands. We have started to use them almost exclusively now if we are traveling the interstates.
Remember, the truckers are their business, not the RVers. The truckers are required to be off the road a certain number of hours per day. We don;t have that requirement. We have plenty of other places we can park.
For me, a truck stop is way to noisy to park at. Trucks going in and out, idling etc.
