2026 Springdale310BR

The Springdale 310BR is a rear double-size bunkhouse with an exterior outdoor kitchen, a front private king bedroom and dual entry doors, under two slides — a 35-foot travel trailer aimed at larger families who want maximum sleeping capacity, a rear bunkhouse and an outdoor kitchen on a steel-framed value trailer. Rear double-size bunks and a front private king bedroom bracket a central living area with a booth dinette, sofa slide and theater seating; an exterior outdoor kitchen, a laundry chute, a tankless water heater and a 30K furnace are standard, dual entry doors ease family traffic, and 50-amp wiring allows a second and third A/C.

It carries Springdale's value build — a powder-coated I-beam steel frame with stamped cross-members and outriggers, laminated sidewalls and a walkable roof membrane, with a 15,000-BTU ducted air conditioner standard, on tandem axles. At 7,815 pounds dry against a 9,820-pound GVWR it leaves 2,005 pounds of cargo capacity, and the dry tongue weight is 1,020 pounds. A 10 cu ft refrigerator and 15K BTU air conditioning round out the equipment.

A figure worth stating plainly: Dry weight (7,815 lb) is from RVingPlanet and General RV family listings, matched on length and slide count; GVWR (9,820) is derived as dry plus the RVUSA cargo capacity (2,005 lb), as no GVWR is published. RVUSA lists a sleep capacity of eleven while dealer sources list nine (belted seating versus sleeping positions); the RVUSA figure is shown. MSRP is not published on RVUSA; the price is dealer-quoted. 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 larger families who want maximum sleeping capacity, a rear bunkhouse and an outdoor kitchen on a steel-framed value trailer, the 310BR is a well-targeted pick within the Keystone value stack.

Keystone's Springdale is a broad lightweight line built on a powder-coated I-beam steel frame with a 15,000-BTU ducted air conditioner standard. The plan on this page is highlighted; each profiled plan links to its own page. The full Springdale catalog runs to many floorplans — the highest-demand layouts are detailed here and the rest are catalogued on the Springdale hub.

This floorplan carries its water comfortably. A full 45-gallon fresh tank is roughly 19% of the 2,005-pound cargo capacity, leaving the 310BR with a usable gear budget even when you tow full.

The published dry tongue weight of 1,020 pounds is 13% of the 7,815-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.

Nothing above changes the ceiling. Loaded to its 9,820-pound GVWR the 310BR is towing 2,005 pounds more than its 7,815-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.

Tank balance is generous here: 45 gallons of fresh against 69 grey and 39 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.

Of the 12 Springdale floorplans profiled here, the 310BR carries the highest GVWR at 9,820 pounds. It is the top of the line by weight, which makes tow-vehicle capability the first thing to settle rather than the last.

Either side of it in the same line: Springdale 245ML is 20 pounds lighter at 9,800 lb GVWR.

Against the 310BR: the Salem Hemisphere & Heritage Glen 261FKRB is 4 ft shorter and sleeps 9 fewer; the Aurora 29TQS is 4 lb heavier and sleeps 3 fewer; the Coachmen Catalina 323BHDSCK is 6 lb heavier and sleeps 2 fewer. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.

Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.

For scale, the Springdale floorplans profiled here run 4,647 to 7,815 pounds dry and 25 to 36 feet of exterior length across 12 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

Every profiled floorplan in this line, with the full weight table, is on the Springdale line hub.

This catalog tracks 18 specification fields per floorplan. Named sources publish 15 of them for the 310BR. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.

Not published for this floorplan: exterior width, interior height, tire specification. If you find one of these in a manufacturer document for this plan, it belongs on this page.

The completeness figure at the foot of this page (88%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.

How every figure here was sourced and checked is set out on the methodology page.
