You could also look for a nearby parking lot and drop the trailer for the few minutes it would take to go refuel the TV.
First time I pulled into a gas station with my F250 crew cab long bed and a 26 ft TT I nearly clipped the pumps even though I swung as wide as possible without hitting the building.
Gas stops are inevitable but are something I try to avoid doing with the 5'er hooked on. When I must, I try to pull up somewhere near and then scope out where the diesel pumps are and the best way to get in and out.
We do look for Flying J's since many of them have RV friendly pump stations.
Best wishes for a safe journey!
