Among the 8 Northern Spirit Ultra Lite floorplans Coachmen’s Northern Spirit Ultra Lite brochure (filed in Coachmen’s /brochures/2021/ folder; the brochure prints no year) lists with a published dry weight, it is number 1 from the lightest, in a range from 4,926 lb (Northern Spirit Ultra Lite 1943RB) to 8,248 lb (Northern Spirit Ultra Lite 3379BH). Every figure in that comparison is Coachmen’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from Coachmen’s Northern Spirit Ultra Lite brochure (filed in Coachmen’s /brochures/2021/ folder; the brochure prints no year); model year 2021 comes from where the maker files it on its own site, not from the document’s text.
