Keystone Cougar Half-Ton 26RES
The maker never published an MSRP for this floorplan. Unknown is not cheap. Treat any asking price against comparable models, not against zero.
dry weight 8,240 lb + fresh water (54 gal, full) 450 lb + propane + battery 200 lb + gear for 2 600 lb. Brochure dry weight omits water, propane, batteries and your gear; this estimate doesn't.
Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 26RES's published weights held steady.

Keystone (Mixed tier): Keystone's half-ton-towable spinoff of the Cougar nameplate, offered as both travel trailers and premium fifth wheels (fifth-wheel floorplans under the Premium Fifth Wheels subline) built light enough for 1/2-ton trucks.
Findable: a few listed nationwide most weeks. Why: Keystone is a volume manufacturer; only one model year; still in production. Estimated from build volume and production span, not a count of live listings.
GVWR derived (Shipping Weight + Carrying Capacity). Collected from a census gap: this line had no catalogue record at all. tier, bn and mat are the collecting pass's editorial read, not inherited from siblings. Slide-out count added by a later pass: SpecsTable row Slides=1
