Damon RV dimensions
Length, beam and height for 6 Damon RV models, from the maker's own spec pages and brochures. Every figure links back to its source and shows the date we last checked it. Where the source reads web.archive.org, the figure comes from a saved copy of the maker's own page. These figures are part of the Vehicle Storage Size Guide.
