IMO 5000 lbs is an overly generous tow rating for such a light vehicle as the XJ Cherokee. Towing almost 4,000 will be real challenge, especially if you are not skilled and experienced with towing. From experience, I would recommend a larger tow rig for that load.
If you choose to continue:
1) Install a transmission cooler.
2) Use 3rd on the transmission, OD will generate too much heat, even with a cooler.
3) Trailer brakes are not optional.
4) Practice towing before your trip begins.
A recent Gallup public opinion poll shows the NRA, at 58% approval, has a higher approval rating than either Hillary Clinton or Barack Obama.
