01 What makes it unique
Gulf Stream lists the Envision 21TBS at 3,576 lb dry, a net carrying capacity of 2,444 lb and a tongue weight of 420 lb. It prints no GVWR for it.
It is 22' 6" long and 10' 6" high. Gulf Stream prints no tank capacity for it.
Among the 16 Envision floorplans Gulf Stream’s Envision model pages on gulfstreamcoach.com (no model year stated) lists with a published dry weight, it is number 5 from the lightest, in a range from 3,160 lb (Envision 18RBD) to 7,117 lb (Envision 290RL). 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 Envision model pages on gulfstreamcoach.com (no model year stated) for the Envision 21TBS, which names no model year; the figures are shown as the maker published them, and no year is claimed for them.
How the 21TBS differs from the other fifteen Envision floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 3,576 lb: shared with the 21QBD; of sixteen, three lighter and eleven heavier, nearest the 21QBS (3,567 lb) and the 21TBD (3,655 lb).
- Tongue weight, 420 lb: shared with the 21QBD and 22UDL; of sixteen, two lighter and eleven heavier, nearest the 19FMB (370 lb) and the 21QBS (440 lb).
- Length, 22 ft 6 in: shared with the 21QBD, 21QBS and 21TBD; of sixteen, one shorter and eleven longer, nearest the 18RBD (21 ft 1 in) and the 19FMB (23 ft 3 in).
- Exterior height, 10 ft 6 in: shared with the 19FMB, 21QBD and three others; of sixteen, one lower and nine taller, nearest the 18RBD (10 ft 4 in) and the 28CRB (10 ft 11 in).
- Cargo capacity, 2,444 lb: shared with the 21QBD; of sixteen, eight smaller and six larger, nearest the 21TBD (2,405 lb) and the 25CBQ (2,470 lb).
- Tongue weight as a share of dry weight, 11.7%: shared with the 21QBD; of sixteen, seven smaller and seven larger, nearest the 24RBS (11.3%) and the 280RB (12%).
Next to the 21QBS, the nearest lighter floorplan by dry weight, the 21TBS is 9 lb heavier by dry weight, has 29 lb less cargo capacity and has a tongue weight 20 lb lighter; the two publish the same length, exterior height and interior height.
Next to the 21TBD, the nearest heavier floorplan by dry weight, the 21TBS is 79 lb lighter by dry weight, has 39 lb more cargo capacity and has a tongue weight 40 lb lighter; the two publish the same length, exterior height and interior height.
On every figure compared here the 21TBS publishes the same values as the 21QBD, so on these numbers alone they cannot be told apart.

No GVWR is printed, so nothing is checked against one. Page footnote: "Specifications are approximate and subject to change. Check the label in your unit for actual weights and capacities."

04 Notes on this floorplan
What Gulf Stream does not publish for the Envision 21TBS
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.

07 Where this floorplan sits
Closest sibling: the Envision 21QBD. The two publish identical figures on all 4 fields both carry (length, dry weight, cargo capacity, hitch weight), so the published record does not tell them apart; what separates them is the floorplan itself.
| Envision plans | This plan | Position, low to high | Range |
|---|---|---|---|
| Dry weight (lb) | 3,576 | 4–5 of 16 | 3,160–7,117 |
| Cargo capacity (lb) | 2,444 | 9–10 of 16 | 740–3,665 |
| Hitch weight (lb) | 420 | 3–5 of 16 | 320–1,020 |
| Length | 22 ft 6 in | 2–5 of 16 | 21 ft 1 in–34 ft 9 in |
Either side of it by dry weight: Envision 21QBD matches it at 3,576 lb dry; Envision 21TBD is 79 lb heavier (3,655 lb dry).
