2026 Bullet Premium310RES

The Bullet Premium 310RES is a rear-entertainment/living layout with three slides, a kitchen island and two awnings — a 35-foot travel trailer aimed at couples who want a large, residential half-ton-towable trailer. Bullet Premium extends the Bullet build to longer, triple-slide floorplans with the openness of a much larger fifth wheel.

It carries the Bullet Premium build — vacuum-laminated sidewalls, an aerodynamic radius front cap, a walkable roof and an enclosed, heated underbelly on longer floorplans, on tandem axles. At 8,300 pounds dry against a 10,585-pound GVWR it leaves 2,285 pounds of cargo capacity, and the dry tongue weight is 1,030 pounds. A 10 cu ft refrigerator and 15K BTU* air conditioning round out the equipment.

A figure worth stating plainly: Dry weight is derived from GVWR minus the RVUSA cargo capacity (2,285 lb) and flagged; confirm against the unit's sticker. As with every lightweight trailer, the published tongue weight is a pre-production dry estimate — once water, gear and passengers are aboard, real loaded tongue weight runs higher and lands on the tow vehicle's payload, so weigh the loaded trailer and match it to your truck honestly before relying on the brochure number. For couples who want a large, residential half-ton-towable trailer, the 310RES is a well-targeted pick within the Keystone value stack.

Keystone's Bullet spans the lightweight aerodynamic Bullet Classic (single- and dual-axle small trailers) and the larger half-ton Bullet Premium floorplans. The plan on this page is highlighted; each profiled plan links to its own page. The full Bullet catalog runs to dozens of floorplans — the highest-demand layouts are detailed here and the rest are catalogued on the Bullet hub.
