I do not know how long they stay in one place at a time, this is not well defined
Two of their caravans came through Roca Azul at the west end of Lake Chapala while we were there. There were 24 units in each caravan. They stayed for 6 days each. They had trip/tours on two of those days but did not appear to have much else to do the other days. We met up with them on another occasion maybe 6 or 7 years ago when they came into Teotihuacan with 22 rigs (in 18 spaces) and had an organized bus trip to Mexico City when they were gone a couple days (not everyone went). I forget how long they were there. They had Green Angel years ago but did not see any this year. That's about all I know.
