This may change but In 13 years I have found one Flying-J that started out and is once again a PILOT that did not have RV parking (13 years ago Flying-J was buying Pilot stations. then about 8 years ago They reversed and Pilot bought out J.) but today I do not think any Pilots have RV parking, though they may have pull through truck parking But not all do.
Most Flying-Js' (all but that one that is now a pilot, Benton harbor MI area by the way) DO have RV parking. though the sites are 20 feet too short for me.
Some LOVES (Fair Play SC is the specific) have RV parking too, same length issue.
Just so you know.
And most Pilots have only a "Fast Food" restaurant, Subway Arbie's McDonalds. Et-al
Many J's have a Denny's which gets me 15% off on my meal when I flash my AARP card they run the bill through the 15% shrikey dink and it gets cheaper :) :)
this is in addition to the "Counter foods"
Some have 2 or 3 food options (Multiple restaurant).
I have only been at one T/A in the last decade. they did not have RV parking but did have a spot where I was able to park for the night.. then Run up to a nearby city with the towed and get a replacement part for my RV and install it.
That T/A.. used to be the TEKON and that is station all the Truck Plaza type centers are patterned after.. But it's a T/A today.. Restaurant is decent but no discount :(
I grew up about 6 miles from that station.
On edit. WOW the Captca worked FIRST TIME EVER it worked right,.
