For what it’s worth:
I contacted Pilot/Flying J via their website “contact us” email. I said that there were many RVers who have placed deposits for the F150-Lightning.
I asked if they would have FCDC sites that would accommodate a truck and trailer.
I was told my request would be passed on...
That's exactly my concern!
I use my current F150, and then the lightning, to pull my travel trailer. Without charging sites that will accommodate truck and 30-40' trailer, the distance on a charge is secondary to getting the truck/trailer into and out of a charging site without disconnecting.
