If I remember right Wisconsin outlawed studded snow tires. Minnesota did not. Minnesota people were driving on studded tires in Wisconsin.
They were allowed to because the state they were from allowed them and they were transient in Wisconsin.
If this is right you should be able to double tow in any state if your state of registration allows recreational double towing. .

Sorry, but your interpretation of the law isn't at all accurate. You can try arguing it in court but first you better read up on the law and understand what you're arguing. In your examples your point is counter to the law. It was always fun to go to court and listen to some guy argue what he thought the law said and it was obvious he'd never read the statute. Great entertainment.
Using your thought process what's the speed limit in WI? If I come from another state with a higher speed limit can I drive the higher speed when in WI? Nope.
To carry your thought process even further, if I'm from MO I am required to wear a motorcycle helmet. So when I ride in WI do I obey WI law or MO law? I hope you can now see why your interpretation of state laws doesn't hold water.

I'm thinking the states that have a laws not allowing double towing are aimed at commercial trucking..

Don't try thinking about it because you're incorrect. Read the law. You'll find it's all explained in your state statutes. Most likely if you do your research correctly you'll find a state statutes addressing both commercial vehicles and RVs.

Years ago I got pulled over by Illinois State Patrol.
The Officer pulled me over for displaying red lights on top of my tow truck.
I told him I had to have red lights on my truck because the State of Wisconsin by law says I must have them.
His answer was your vehicle is not private registered your vehicle is registered as a commercial vehicle therefore you have to obey Illinois law which says only amber lights on tow trucks.
He made me cover my red lights with a tarp before proceeding any further.
Thankfully he didn't cite me.

You just provided a good example of how you obey the laws of the state you're driving in. Doesn't matter what WI law says. Once you cross the state line then you obey the laws of that state. You could have been cited. You got a break.
I can't begin to count the number of times I stopped someone from out of state and they were quick to argue that whatever they were doing was legal in their home state therefore it was legal in IL. Remember the line from the Wizard of Oz. "We aren't in Kansas anymore Toto."
