Solitude 310GK

The compact end of the Solitude lineup, with the lowest published dry weight and the most cargo headroom in this ten-floor-plan set.

The outline is a generic fifth-wheel shape, not a profile of this unit. Roof sits 1 in under a 13 ft 6 in limit. Overall length is 5 ft 8 in shorter than a 40 ft pad. 13 FT 6 IN CLEARANCE 13 ft 5 in 34 ft 4 in overall 40 FT PAD Roof: 1 in under a 13 ft 6 in limit Length: 5 ft 8 in shorter than a 40 ft pad SCALE DRAWING FROM PUBLISHED DIMENSIONS

Drawn to scale from the published 34 ft 4 in length and 13 ft 5 in height, on a generic outline: 1 in under a 13 ft 6 in roof limit and 5 ft 8 in shorter than a 40 ft pad.

Why the 310GK belongs on a different shortlist

The 310GK is the size-first Solitude choice. Its 34 ft 4 in published length makes it the only detailed Solitude record under 35 feet, while the rest of the lineup begins at 37 ft 10 in. That difference is large enough to matter when a buyer is screening storage spaces and campsite length limits before comparing interior details.

Who this floor plan fits

Start here if the goal is Solitude-level specifications without automatically moving into a 40-plus-foot trailer. The 310GK is also the lightest record in this lineup, so it gives weight-conscious shoppers a logical first benchmark rather than asking them to compare every larger plan at once.

Tradeoff to examine: The smaller footprint is the reason to shortlist this model, but dimensions alone do not establish whether its room arrangement or storage works for a specific household. Review the official floor-plan drawing and walk the exact unit before treating the shorter length as an all-purpose advantage.

Weight implications for the 310GK

Using the year-specific figures in this record, the 310GK has 6,500 lb between its 12,500 lb dry weight and 19,000 lb GVWR. That is a rating comparison, not a promise that a particular trailer can carry that amount after options, fluids, batteries, and dealer-installed equipment.

Its published 2,350 lb pin weight equals about 18.8% of recorded dry weight. Loaded pin weight can change substantially, so this percentage is useful for comparing brochure records but not for approving a tow vehicle.

Within these ten Solitudes, this record ranks 1 of 10 from lightest to heaviest and 1 of 10 from shortest to longest. Check the truck's payload label, rear-axle rating, tire ratings, hitch, passengers, and cargo against the exact trailer before towing.

Capacity in practical context

Fresh water 83 gal
Gray water 106 gal
Black water 53 gal

At 83 gallons fresh, 106 gallons gray, and 53 gallons black, the recorded tank package matches several longer Solitude layouts. Its distinguishing capacity number is the 6,500-pound difference between published dry weight and GVWR, the largest calculated margin in this ten-record lineup.

Tank values are kept separate and shown exactly as represented in the year-specific source. Actual usable capacity and installed equipment should be confirmed on the unit.

310GK comparisons that change the decision

What to test during a 310GK walkthrough

  • Measure the available storage or driveway before assuming every site labeled for a 35-foot RV will accept the full trailer, hitch clearance, and tow vehicle.
  • Walk the main aisle with slides both open and closed, noting whether the refrigerator, bathroom, and bedroom remain reachable during travel stops.
  • List the gear normally carried for a long trip, then compare that real load with the exact unit's cargo label rather than the brochure subtraction alone.
  • Compare interior storage against the 370DV in person; the 310GK's shorter body is valuable only if the cabinetry and basement still hold the buyer's essentials.

Source note

The official 2026 brochure lists 12,500 pounds dry. An unlabeled current official page lists 13,200 pounds, so the year-specific brochure value is used here and both sources remain preserved.
