I don't know the answer of who, but I've always been interested in the Ridgeline as a Toad. I did see a gent towing one four down in New Mexico. He was going the East, while I was going West - so I had no way to ask him any questions.
Official answer remains no, but sure would be interested if others have done so successfully too...
Will follow this thread if anyone pops in with more info. I have searched this a few time on this and other boards too
Best to all, have fun, be safe,
