Has anyone ever been stopped for this? I see rigs on Hiway 60 in Arizona from all over the country towing a second trailer or jeep four down. Chris

Yes I've seen it. A lot of times. Spent 42+ yrs in LE and it's a fairly common stop.
Just because you haven't seen it doesn't mean it didn't happen. It only means you weren't on that particular piece of roadway at the exactly right time to be there when the stop was made.
