As do I.
Do you think that could be the device the second trailer sits on when over-the-road truckers use? I have seen these towed with the second trailer missing.
Bet if you checked you would find the fright-hauler pulling the dolly behind a trailer is a)running routes/states that allow CMV to tow doubles, and b)the CDL states driver has passed test to tow double/triples. BYW, the endorsement is for doubles
and triples. Likely because some state might call the converter dolly a trailer.
And while doing the grape/grapefruit comparisons;

The swivel wheel company that I bought mine were very specific about not claiming it "NOT" to be a trailer. They stated that some states considered them trailers, and it was the responsibility of the owner of the trailer to find out the particulars for their case.
Last company I was leased to had what we called a stinger. It worked kinda like a swivel wheel trailer, in that it pined solid to RGN. (Your SWT has load put on it, and pivots up/down so does not lift 5th. wheel. Stinger, OTOH pined solid, no movement between it and trailer. Had no load deck, but was adjusted to take some weight off trailer axles. Less like trailer than the swivel wheel). If the stinger was in place the driver had to have double/triple endorsement
