The Pop-Up That Grew Up: 2026 Forest River Flagstaff Hard Side Series T21HS
Meet the 2026 Forest River Flagstaff Hard Side Series T21HS—the A-frame camper that proves you don't have to choose between the easy towing of a pop-up and the solid-wall security of a traditional travel trailer.

Whether you're a weekend warrior or a cross-country explorer, this clever little rig gives you the absolute best of both worlds. It folds down for aerodynamic, fuel-efficient towing, but pops up to offer a fiberglass-laminated roof and durable hard sides that keep the weather (and the wildlife) exactly where they belong: outside.

Why you'll love it:

The Comforts of Home: Forget shivering in a tent! This rig is equipped with an 11K Under Bunk AC for the summer scorchers and a 20K BTU Furnace for crisp autumn mornings. It even features a built-in Port-A-Potty (exclusive to the T21HS), so you can skip the midnight hike to the campground bathhouse.

Gourmet on the Go: The Andover Sable wood interior hosts a remarkably capable kitchen. With an indoor range, a water filter, and a 12V refrigerator, you have everything you need to whip up something better than burnt hot dogs.

Off-Grid Capable: Want to escape the crowded RV parks? Thanks to the 125W roof solar panel and onboard battery box wiring, you can keep your lights on and your drinks cold even when you're boondocking in the wild.

Tow with Confidence: Weighing in at a feather-light 2,728 lbs (Dry Weight), you won't need a heavy-duty monster truck to haul this beauty. Plus, with Dexter Torflex Axles and electric brakes, it tows like an absolute dream.

The Quick Specs:

Condition: Brand Spanking New

RV Type: Hard Side Pop-Up Camper (Sleeps up to 4!)

Weight: 2,728 lbs Dry

Length: 20 feet (240 inches of pure camping magic)

Hitch up, pop the top, and get ready to be the absolute envy of the campground. The open road is calling, and it wants you to answer in smart, hard-sided style!
