We traveled from Arizona to the east coast and back last summer with a 35 ft Class A gas motor home. Many of the gas stations were situated with the pumps angled towards the convenience store so without a lot of work, we couldn't use them. Pilot/Flying J has a brochure that lists all of their stations and identifies what services are available, such as an RV lanes. You can download this in PDF also. In general, I was disappointed with the TA station access. They seem to be set up for cars in front and diesel trucks in back but not for gas RVs. Some Walmarts had good pull through lanes. This summer we will be towing a vehicle so we will have to be more careful!
