You can tow behind a larger vehicle with no problem. The horror stories cone when the pulling vehicle is the same weight or less. That's when the Jeep acts more like a pendulum, swinging side to side and dragging the pulling vehicle with it. A heavy pulling vehicle will keep the Jeep in check.
As far as the front axle, it would be best to have lock out hubs installed, so it keeps the front axle from turning. As a tip, I would invest in a thermal temp gun. This can be used to take temperatures of the hubs and rear axle from time to time to ensure all bearings are happy along the trip. The temp gun allows you to point it at housings without crawling underneath.
