Margo recently passed these on to me. I haven’t looked at the sites very carefully. Maybe they will help you. Maybe they won’t.
Big Truck Stops. An android app. Shows only the top 5 truck stops, Flying J, Pilot, Loves, Petro and TA Travel Centers. For those of us who need more room to get to the gas pumps.
RV Parks and Campgrounds. An android app. Free with no ads. 4.6 reviews.
Wheeling It Master Campground Map. A couple who has been RVing since 2010. Click on the icons to see where they’ve stayed.
