I have a 2012 Thor Palazzo 33 ft diesel class A. I tow a Lincoln MKZ hybrid using a blue ox tow bar. I have noticed when I execute a left turn to a road that is pitched to the right at a slow speed I get what feels like a wheel wobble(almost like a flat tire). When I straighten out it goes away but it is very alarming. Any ideas?

Is the steering wheel unlocked?

It's called bump steer and is quite common in vehicles with electric steering, like your MKZ. It will only happen at low speeds while transitioning a change in surface conditions and/or elevation and turning.

One way to lessen it is to loop a bungee cord through the steering wheel a couple of turns and secure both ends under the drivers seat. This will keep a centering tension on the steering thus preventing the back and forth bump steer.

Not sure the "thor" has the ump to pull anything other than a Fiat 500.

Doesn't Cummins and Freightliner do the grunt work?

I'm pretty sure that you are right. I didn't see the chassis or engine fabrication during our plant tour at Thor. They looked to me like they arrived already built.

But then, Thor products are open game for anything and others are protected.

Using a bungee cord is commonly done in certain vehicles to prevent wobble. I've done this for over 3,000 miles. The cord is just tight enough to stay hooked up.
