WHAT ONE COSTS

The maker never published an MSRP for this floorplan. Unknown is not cheap. Treat any asking price against comparable models, not against zero.

WHAT IT WEIGHS BEHIND YOUR TRUCK

~10,429 lbestimated as towed, for 2 people

dry weight 9,179 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.

You want a tow rating around11,590 lb (10% margin)

GVWR (the sticker maximum)11,000 lb

Tongue weight, loaded~1,630 lb (16%: high, eats payload)

WHICH TOW VEHICLES IT FITS: 30 OF 95

Judged the way the app judges: estimated loaded weight against each vehicle's rating less a 10% margin, per model year, because the 28RLI'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.

FINDING ONE

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.

OUR TAKE

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=2
