Esterel production was stopped in 2001 when Rapido had take back the production unit. The Rapido factory (and other trademarks)transformed their units to produce a lot of camping cars (new mode of hollidays) at the begining of the 21th century. Rapido, Fleurette, Casita etc... will stop the folding produtions at the same time.
Today, only one factory make "folding caravans" yet. Ace-Lebrun, made in spain and distribute by Lebrun & fils, north of France http://www.ace-caravans.com/especiales
Many french distributors actually says that caravans are back and camping car sales are lesser.
Maybe an happy new year for our folding caravans...
