I *think* we have the same camper, and we have a 2015 Jeep Cherokee (not grand, just the cherokee) Trailhawk where the center of our 2" receiver box is about 21" off the ground - so I may be familiar with your situation. Our GS camper is a 2013 19ERD (also called the VISA) that is very low to the ground with little ground clearance and designed to step directly into the camper (ie, no external steps on the camper to be lowered). If that sounds right for your camper, then it is probably similar to ours. When our camper is level on a level surface, the bottom edge of the hitch is approximately 13" off the ground. Our weight distribution/anti sway hitch has height adjustments to put the ball at the correct level, and it is almost at the lowest possible setting. We also happen to have a . Visually the receiver on the jeep and the hitch on the trailer are *way* out of line and without a significant drop hitch the back end of the camper would probably be touching the ground (at least the stabilizer jacks would be). We actually tow this with my 2WD pickup because I like the extra power of the V8, so I don't have a direct solution but figured the information I do have could be useful. Pictures below:
