Did all dodge mini van models have the sto-go systems in 2005?

No, not all Dodge minivan models in 2005 were equipped with the Stow 'n Go seating system. The Stow 'n Go feature was introduced in the 2005 Dodge Grand Caravan and Chrysler Town & Country models, but it was not available in the base models or other variants. Some models offered traditional seating configurations instead.
