Drop hitches work either way. Have you considered how much stress the ball will take especially when braking?
You have to decide how fast is too fast when you tow. You will get answers all over the map on this, but I will say I've towed a Wrangler of one sort or another over 100K now. I've been up to 75, but I don't like it, and I was towing with a much heavier tow vehicle than you will be. You will experience more sway when towing with the shorter wheelbase of a pickup vs a motor home.
I'd also recommend that you carefully check your owners manual about towing several thousand pounds without brakes... I think you may find that your owner manual will specify supplemental brakes as the hitch isn't designed for the kind of stress an emergency stop from 70 would put on it with a 4K towed vehicle.
Do you have emergency brakeaway capability. If you forget to hitch it up right (which is the #1 cause of towing accidents), the ball brakes off and the safety chains don't do the job, your Jeep will be a deadly missile completely out of control if something bad happens.
Folks say all the time that they tow without supplemental brakes just fine. It will only take one panic stop without them to change your and someone else' life so consider that please.
The safest way to tow unless you spend the bucks for brakes is a trailer. Get a U-Haul!
As a final thought, if you still don't believe me, how about a little science to go with it...

Only you know how much risk you are willing to take, but be sure to understand the potential consequences.
