01 What makes it unique
Winnebago lists the 2017 Spyder 28SC at 8,860 lb dry, a GVWR of 12,000 lb and a tongue weight of 1,240 lb. Winnebago prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 34'11" long and 12'4" high. Winnebago prints its tanks as 100 gal fresh, 52 gal grey, 52 gal black.
Among the 4 Spyder floorplans Winnebago’s 2017 Spyder brochure lists with a published dry weight, it is number 2 from the lightest, in a range from 6,940 lb (Spyder 24FQ) to 9,940 lb (Spyder 32SC). Every figure in that comparison is Winnebago’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from Winnebago’s 2017 Spyder brochure, the maker’s own dated document for model year 2017.
How the 28SC differs from the other three Spyder floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 8,860 lb: second-lightest of four, between the 24FQ (6,940 lb) and the 29KS (9,060 lb).
- GVWR, 12,000 lb: second-lowest of four, between the 24FQ (10,400 lb) and the 29KS (12,400 lb).
- Tongue weight, 1,240 lb: second-heaviest of four, between the 32SC (1,160 lb) and the 29KS (1,320 lb).
- Tongue weight as a share of dry weight, 14%: second-largest of four, between the 32SC (11.7%) and the 29KS (14.6%).
- Length, 34 ft 11 in: second-longest of four, between the 29KS (32 ft 2 in) and the 32SC (38 ft 11 in).
- Grey tank, 52 gal: largest of four, level with the 32SC; next are the 24FQ and 29KS (41 gal).
- Black tank, 52 gal: largest of four, level with the 32SC; next are the 24FQ and 29KS (41 gal).
Next to the 24FQ, the nearest lighter floorplan by dry weight, the 28SC is 1,920 lb heavier by dry weight, has a GVWR 1,600 lb higher, has a tongue weight 480 lb heavier, is 4 ft longer, stands 5 in taller, has a grey tank 11 gal larger and has a black tank 11 gal larger; the two publish the same interior height and fresh tank.

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 (12,000 lb) and the upper loaded tongue estimate (1,800 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). The range starts at the published figure, because loaded is never lighter than that.

04 Notes on this floorplan
What Winnebago does not publish for the Spyder 28SC
Winnebago prints no cargo carrying capacity, 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
6,940 lb dry and 10,400 lb GVWR, against this model’s 8,860 lb and 12,000 lb.
9,060 lb dry and 12,400 lb GVWR, against this model’s 8,860 lb and 12,000 lb.

11 NHTSA safety record
NHTSA holds 1 recall campaign and 1 owner complaint (model years 2005 on) against the Spyder line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 1 complaint has been filed on this line — not enough to say what fails most often. It covers electrical system.
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 Spyder line page.
