FWIW my opinion of FJ RV fueling stations is they are no easier than the regular pumps, and in many cases, more difficult. The typical FJ RV fueling station is designed to funnel the customer out and toward the store and also straight into a car parked at the store. I've actually had to wait at a fueling station until the "customer" at the store left, and then I was able to pull out. Entirely possible he will run into that same situation. I've seen many trailers being pulled thru the regular pumps as most FJ sites have large and roomy parking lots.
It is a common problem RVers have with no easy solution except to get better at handling the tow.
