01 What makes it unique
Gulf Stream lists the Enlighten 21RBS at 4,360 lb dry, a net carrying capacity of 3,027 lb and a tongue weight of 400 lb. It prints no GVWR for it.
It is 22' 11" long and 11' 2" high. Gulf Stream prints no tank capacity for it.
Among the 6 Enlighten floorplans Gulf Stream’s Enlighten model pages on gulfstreamcoach.com (no model year stated) lists with a published dry weight, it is number 4 from the lightest, in a range from 2,810 lb (Enlighten 17BH) to 5,460 lb (Enlighten 27BHS). Every figure in that comparison is Gulf Stream’s, read from the same set of model pages.
Every number on this page was read on 6 Nov 2026 from Gulf Stream’s own Enlighten model pages on gulfstreamcoach.com (no model year stated) for the Enlighten 21RBS, which names no model year; the figures are shown as the maker published them, and no year is claimed for them.
How the 21RBS differs from the other five Enlighten floorplans. Most distinctive first. How these ranks are worked out.
- Exterior height, 11 ft 2 in: tallest of six; next is the 27BHS (11 ft 1 in).
- Cargo capacity, 3,027 lb: second-largest of six, between the 21RK (2,940 lb) and the 25BH (3,601 lb).
- Tongue weight as a share of dry weight, 9.2%: second-smallest of six, between the 25BH (9%) and the 17BH (11.7%).
- Dry weight, 4,360 lb: third-heaviest of six, between the 25BH (3,899 lb) and the 21RK (4,620 lb).

- Length, 22 ft 11 in: third-shortest of six, between the 17BH and 17RB (20 ft 11 in) and the 21RK (25 ft 6 in).

04 Notes on this floorplan
What Gulf Stream does not publish for the Enlighten 21RBS
Gulf Stream prints no GVWR, tire size, grey-tank, black-tank, sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
