You can't tow the 2185; it has a dry hitch weight of 730 lbs, and when loaded for camping with LP, battery, etc, the hitch more likely will weigh 800-900 lbs. That's too much for your suspension. The 1995 is a better candidate, but at almost 24' length you will
definitely need an anti-sway, weight-distribution hitch (such as the Equal-i-zer)... this will add about 85-90 lbs.
In the flatlands at about 55-60 mph you should be ok. Wind resistance goes up exponentially as one speeds up. If you want to go to the mountains, plan on 35-40 mph up the grades.
I know there have been one or more Chrysler engineers on this forum in the past. But if you don't get what you're looking for, you might try one of the Jeep-specific forums.

Liberty is meaningless where the right to utter one's thoughts and opinions has ceased to exist. That, of all rights, is the dread of tyrants. --Frederick Douglass
