Do they stick out farther than the jacks?
I have the torklift tie downs on my 2017 F350 (not dually). They have two holes and I have mine on the holes that put them closer to the truck. If memory serves, they are not far from bottoming when using those holes, so I don’t think there is much to be had as far as getting them in closer. If you do bring them in closer, make sure you secure the camper from moving side to side in the bed which could result in the stabilizers making contact with the side of the bed. Also watch the gas door access. I can barely get mine open enough for the gas nozzle when the stabilizers are installed.
