F150 or F250

I'm easily confused but "left us stranded on the side of the road" and "it wouldn't go smoothly into a parking space after TT was unhooked was a sign." so which was it and how did it get to the dealer? I'll go out on a limb and say you had trouble backing into the campground site and it was up hill taking several tries to get parked. This will overheat the tranny and blow oil out because R is not as high a ratio as 1st. If it's a 4X4 next time us Low range if having to back uphill.
Camper's have a way of growing so I'd be looking for a F250.
