01 What makes it unique
Casita lists the 24′ Discovery FM at 4,300 lb dry and a GVWR of 6,000 lb. It prints no tongue weight for it. Casita prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 24'3" (Tongue to Bumper) long and 9'6" high. Casita prints its tanks as 45 gal fresh, 40 gal grey, 35 gal black.
Among the 7 Casita floorplans Casita’s model pages on casitatraveltrailers.com (no model year stated on the spec tables) lists with a published dry weight, it is number 6 from the lightest, in a range from 2,000 lb (15′ Patriot) to 4,300 lb (24′ Discovery LC). Every figure in that comparison is Casita’s, read from the same set of model pages.
Every number on this page was read on 6 Nov 2026 from Casita’s own model pages on casitatraveltrailers.com (no model year stated on the spec tables) for the 24′ Discovery FM, which names no model year; the figures are shown as the maker published them, and no year is claimed for them.
How the FM differs from the other six Casita floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 4,300 lb: heaviest of seven, level with the LC; next are the Heritage, Independence and two others (2,260 lb).
- GVWR, 6,000 lb: highest of seven, level with the LC; next are the Heritage, Independence and three others (3,500 lb).
- Length, 24 ft 3 in: longest of seven, level with the LC; next are the Heritage, Independence and two others (17 ft).
- Exterior height, 9 ft 6 in: tallest of seven, level with the LC; next are the Heritage, Independence and three others (8 ft 11 in).
- Interior height, 6 ft 7 in: tallest of seven, level with the LC; next are the Heritage, Independence and three others (6 ft 2 in).
Next to the Heritage, the nearest lighter floorplan by dry weight, the FM is 2,040 lb heavier by dry weight, has a GVWR 2,500 lb higher, is 7 ft 3 in longer, stands 7 in taller and has 5 in more interior height.
On every figure compared here the FM publishes the same values as the LC, so on these numbers alone they cannot be told apart.

04 Notes on this floorplan
What Casita does not publish for the 24′ Discovery FM
Casita prints no cargo carrying capacity, tongue weight, tire size, 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.
05 How it compares
2,260 lb dry and 3,500 lb GVWR, against this model’s 4,300 lb and 6,000 lb.
4,300 lb dry and 6,000 lb GVWR, against this model’s 4,300 lb and 6,000 lb.
06 Loading it for a trip
No source publishes a tongue weight for the 24′ Discovery FM, so its hitch load has to come from a scale ticket taken with the trailer hitched.
07 Where this floorplan sits
Closest sibling: the Casita 24′ Discovery LC. The two publish identical figures on all 6 fields both carry (length, dry weight, GVWR, fresh tank, grey tank, black tank), so the published record does not tell them apart; what separates them is the floorplan itself.
| Casita plans | This plan | Position, low to high | Range |
|---|---|---|---|
| GVWR (lb) | 6,000 | 6–7 of 7 | 3,500–6,000 |
| Dry weight (lb) | 4,300 | 6–7 of 7 | 2,000–4,300 |
| Length | 24 ft 3 in | 6–7 of 7 | 15 ft 0 in–24 ft 3 in |
Either side of it by GVWR: Casita 17′ Spirit is 2,500 lb lighter (3,500 lb GVWR); Casita 24′ Discovery LC matches it at 6,000 lb GVWR.
