among our coaches we drove a 36 gasser with tow'd for 110,000 miles over 8 years. Flying J were the easiest most of the time at their RV Islands most other truck stops we avoided. Looked for older stations with islands parallel to the store front. Once or twice we had to disconnect the tow'd and maneuver backwards to get out, that was in early years.
First rule was begin looking to a fuel stop before getting below 1/2 tank. That relieves the pressure to pull into an unsuitable/questionable location.
We are always "on the road" so we have become quite qdept at this.
