Plan on long stopping distances. A jeep makes a heavy trailer for having no trailer brakes.
Make sure your Jeep has some caster in the alignment, or the front wheels of the towed vehicle will not follow you well, particularly around sharp corners.
If you do have to back up, lock the steering wheel of the towed vehicle by turning off the key first. The wheels will quickly turn to full lock as you back up otherwise.
The tow bar should be flat (level) while towing for the best ride. If not, the towed vehicle will push/pull the towing vehicle over every bump. The greater the angle of the tow bar, the worse this effect becomes. BUT - having the tow bar slightly lower at the hitch is a little safer for hard braking situations. This is because the rear of the tow vehicle will lift under braking conditions, allowing the towed vehicle to try to drive under the tow vehicle and lift the rear even more, causing a loss of rear wheel traction and potentially a jackknife situation.
I know you already have the tow bar, but the longer your tow bar is, the more control you'll have over the towed vehicle because of increased leverage. We built a 54” tow bar and it was night and day better to tow with than a standard 36” bar. The only disadvantage was a little added air resistance on the highway due to the extra space between vehicles. Well, that and the fact that it was huge.
Hope this helps.
