Hitching and unhitching a 5th wheel

The largest concern I would have is pushing the landing gear sideways, high hooking or the trailer sliding back if the pin is too low (lifting camper while coupling). The pin would need to be almost exactly the same height as the jaws. Normally when you push back the wheel chocks take that load, side coupling the landing gear will take that load or worse lift and the trailer slide off the 5th wheel. Would not do it often and I'd make sure everything was just perfect. Once coupled I'd eyeball the jaws, pull it out and give it a good tug to make sure it was properly coupled.
