Would you flat-tow an MJ with a KJ to Illinois and back?

[Pete M]

The Diesel KJ is rated for 5k lbs. The MJ probably weighs 4k. I've got two 31" tires that I can put on the front or back of the MJ in place of the 33x12.5" swampers. Previously I towed the MJ with a Durango and it seemed to do fine when I put the little 31s on the front axle. Would there be a difference with the 31s on the rear axle? The rational for using the 31s is that they won't follow every single rut in the highway the way that the 33s do and that should keep the sway down. I'm just not sure if it's the front tires or the rear that are the worst offenders.
The reasons I'd be using the KJ is that that's what the owners of the Durango got when the lease on the durango was up, my uncle doesn't have any miles to give on his truck, a good friend recently totaled his longbed 4door chevy, another friend's Bronco has taken a turn for the worse (plus it gets around 8mpg empty anyway). The trip is the weekend of the 24/25th of June and I've run out of options to get to Rockport. And no, after that "funny noise" episode at last year's pig-gig, I no longer trust the engine in the MJ to make it there and back.
Any suggestions on making this as safe as possible? I'm not going to exceed 65 mph and have thought about building an anti-sway devise between the hitch and tow bar. I saw one that was just a friction-plate of sorts.

This is the towbar setup I have, connected to the Durango in this pic.

Yes,
But i'd leave plenty of room for error and i would imagine the "'pucker factor" could get high

Oh, and I forgot to mention that the KJ has a 242 and the allwheeldrive WILL be engaged for the entire trip. It made a big difference last month when I pulled about 2000 lbs of trailer in the rain.

I've seen worse- A KJ pulling a full trailer with a SOA CJ7 out of my driveway and out to Rockford. A different KJ tow dollying the same SOA CJ all the way from KS to IL. Yet another KJ tow dollying a different CJ7 to the Badlands and Cliffs.

Not my idea of a Fun Time, but it can be done....
