To Grit Dog's point about the hitch extension not needing to extend all the way to the back of the camper, here's my setup. The Northstar 12STC camper has 4' of overhang behind my truck bed. The hitch extension is 34" long. It works fine, but if the trailer is 45 degrees or so from straight with the truck & camper, and the trailer is uphill of the truck & camper, the gravel guard on the trailer will scrape paint off the rear jack. I've had to repaint a couple times. And it is a bit of a pain to hook and unhook the trailer.

Perzactly!
And if your trailer was a v nose you’d get more rotation before hitting with the same extension length.
Good visual you provided for those who are hard of understanding!
Another example, the old toyhauler vs my v nose enclosed sled trialer.
Towed the sled trailer everywhere jack knifing it into spots, whatever.
Same hitch stinger, couldn’t turn more than maybe 70deg with the toyhauler (square nose) before the trailer would munch the tail lights on the truck. And the tongue was slightly longer on the toyhauler.
