Travellers are a minority ethnic group. The term ‘gypsy’ is appropriate to a group of travellers from Romany - Romany Gypsies and, as far as acceptable language is concerned, the term ‘Romany Gypsy’ is fine provided it relates to this minority ethnic group.
The perceived casual racism in the post would relate to the OPs notion that the people in the van ‘must’ have come from the traveller site. That may be true but there may have been a stereotyping to presume that they did.
