It's actually Amigos Rodantes and is French. Caravanas de Mexico is the only company running english language ones. FYI, Gabe, Caravanas are now only doing Yucatan in even years. Fantasy still does a trip to Puerto Penasco.
Caravanes Soleil, also out of Quebec, wanted to start the Yucatan but he won't do it with less than 20 rigs. I told him he was crazy to attempt that route with that many rigs, especially since most are large Class A's towing cars. Caravanas did it last year with 12, and it was tough.
