Trigano
Website: www.trigano-camping.com
Trigano is of course the name of a French multinational conglomerate that owns a wide selection of motorhome brands (including, in this country, Auto-Trail, Autosleepers and Marquis Leisure). But it’s only when it comes to awnings that the company uses its name actually on a brand.
Trigano awnings used to be called Eurovent. They come in a wide variety of shapes and sizes, and include the poled models Ocean, Prima, Goa and Guerande, and inflatable models including the Lima, Lagoon and Aruba.
