01 What makes it unique
Grand Design publishes an unloaded vehicle weight (UVW) of 5,361 lb and a GVWR of 6,395 lb for the 2027 Imagine XLS 21MBE, with a hitch weight of 560 lb. It does not publish a cargo carrying capacity on the floorplan page, so none is shown here, and none is worked out by subtracting one published figure from the other. The trailer’s own federal weight label, inside the door, carries its cargo capacity as built.
It is 24' 11" long, 10' 5" high and 8' wide, with 37 gal fresh, 45 gal grey and 37 gal black tanks as Grand Design lists them. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank adds roughly 307 lb before anything else is loaded.
Among the 4 Imagine XLS floorplans profiled from Grand Design’s 2027 pages, it is number 2 of 4 by unloaded weight, in a range from 5,358 lb to 5,711 lb. Every figure in that comparison comes from the same Grand Design page type for the same model year.
Every number on this page was read on 19 Oct 2026 from Grand Design’s own floorplan page for the Imagine XLS 21MBE, whose structured data names the model year 2027. Grand Design marks this floorplan as dealer stock.
How the 21MBE differs from the other three Imagine XLS floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.
- GVWR, 6,395 lb: lowest of four; next are the 22BHE, 22MLE and 23LDE (6,995 lb).
- Tongue weight, 560 lb: lightest of four; next is the 23LDE (650 lb).
- Tongue weight as a share of dry weight, 10.4%: smallest of four; next is the 23LDE (11.4%).
- Length, 24 ft 11 in: shortest of four; next is the 22BHE (25 ft 4 in).
- Exterior height, 10 ft 5 in: lowest of four; next are the 22BHE, 22MLE and 23LDE (10 ft 10 in).
- Dry weight, 5,361 lb: second-lightest of four, between the 22MLE (5,358 lb) and the 22BHE (5,698 lb).
- Sleeping capacity, 5: largest of four, level with the 22BHE; next are the 22MLE and 23LDE (4).
Next to the 22MLE, the nearest lighter floorplan by dry weight, the 21MBE is 3 lb heavier by dry weight, has a GVWR 600 lb lower, has a tongue weight 104 lb lighter, is 1 ft 2 in shorter, stands 5 in lower and sleeps one more; the two publish the same fresh tank, grey tank, black tank and slide-out count.
Next to the 22BHE, the nearest heavier floorplan by dry weight, the 21MBE is 337 lb lighter by dry weight, has a GVWR 600 lb lower, has a tongue weight 93 lb lighter, is 5 in shorter, stands 5 in lower and has one fewer slide-out; the two publish the same fresh tank, grey tank, black tank and sleeping capacity.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (6,395 lb) and the upper loaded tongue estimate (959 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433).
03 The Imagine XLS floorplan family
Grand Design lists 8 Imagine XLS floorplans for 2027. 4 without an existing page here are profiled from Grand Design’s own floorplan pages, from 5,358 lb to 5,711 lb unloaded; the others link to their existing pages. Grand Design publishes UVW, GVWR and hitch weight for these trailers, and no cargo carrying capacity.

04 Notes on this floorplan
What Grand Design does not publish for the Imagine XLS
No cargo carrying capacity appears on Grand Design’s floorplan pages for this series, so that row reads as not published. Nothing is filled from a sibling floorplan, 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.
05 How it compares

11 NHTSA safety record
NHTSA holds 15 recall campaigns and 65 owner complaints against the Imagine line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 65 complaints filed on this line the most-reported components are tires (20%), suspension (18%) and structure (17%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Imagine line page.
