I towed several different Jeeps with a similar towbar, bolted to the front bumper.
It worked. And, it worked well! The really important part, it only cost $145!
When not towing, I used the safety chains to tie the towbar up. That worked just fine, as well.
Yes, it is my understanding that one can not do that in California. But then, We have never taken the motorhome to CA, and it is doubtful we ever will.
Here in Montana, though, I used to run around with the towbar sticking up on the front of the Jeep all summer long, no problem.
