RV tours in Baja, Mexico

Haven't taken one of their tours but have run across them south of the border quite frequently. They seem to be better mannered than most of their competitors but still have a tendency to take over any park they stop at. If I were to take a caravan tour, I think I'd go with either one of the baja travel clubs, Discover Baja or Vagabundos del Mar, as they are usually cheaper and smaller; or maybe join one of the many tours posted on Baja Nomads forum. These are normally run by either local guides or expats and are real small.

My rig is gas but I've been told by a friend who owns a Pemex in Baja Sur that all of Baja now has ULSD. It comes from US refineries.
