Steering wheel locks up on Toad

We are towing a'98 Jeep Grand Cherokee Laredo 4-down behind our 2015 Thor Axis MH. We are using a Roadmaster Towing setup. The Jeep ignition is in the ON unlocked position, transmission in PARK and Transfer Case in Neutral.
The problem is that the Jeep steering wheel will rotate 180 deg and lock. This happens sometime during the trip. I don't feel any change in the MH steering and don't discover the condition until we stop and check it. We also discover that the tow bar is in a stressed condition. All the joints are tight and hard to release.

Any suggestions would be appreciated.

Tripper, you can Bungie the Steering Wheel down so it can't turn but a small amount. That is what I did when I towed a VW Baha with my "B".
BTW, If you lock your wheels straight ahead you can BACK your Dingy if it is 4 down (NOT on a Dolly) just like a trailer. There will be a very, very minimal extra wear on the tires. Don't forget to unlock the Steering Wheel when moving forward.
