I tow a 2015 Grand Cherokee (WK2) with a 2018 Greyhawk 29MV
No problems at all. Tows great. I never thought I would, but sometimes I actually do forget it's back there. The only time I really KNOW it's there is when I'm pulling a long grade, or if I've driven the Greyhawk without the Jeep a while, then I attach it.
I use all Blue Ox tackle with a Patriot II brake. I used the diode kit for lighting, and added the supplemental charge line to keep the battery topped up in the GC. Takes me about 3 minutes to connect/disconnect, and another minute to place and set up the brake module.
I generally cruise around 65 mph (yes, using the cruise control) with Tow/Haul mode engaged. If I'm in an urban area going over overpasses or in hilly terrain, I'll still use cruise control, but will help manage the throttle manually. I'll goose the throttle a little to get a one-gear downshift before a grade and most of the time I can maintain speed. If I let cruise handle it, it will bleed 5 mph and then drop 2 gears trying to make it back up. If it's shifting a lot or I know it's a long pull up a grade, I'll disengage cruise and do it myself to keep the transmission happy.
I researched the vehicle extensively before I purchased it as well as all the tackle, and I installed it all my self. So if you have any questions, I can probably answer them. Just ask away.
ETA: Some differences between our rigs (2015 to 2018): The 2018 has 6-spd transmission; 2015 is 5-spd. The 2018 has true 7500 towing capacity supported by GCVWR AND hitch rating. Some of the documentation for the 2015 model shows 5,000 lb towing capacity, even with a GCVWR of 22,000 lbs. You'll want to make sure both the weight rating and the hitch itself support 7500 lbs. 5,000 lbs rating with a 4875 lb vehicle is a little close for comfort IMO, but then I put stuff in my Jeep and use it a little like extra storage...
