Solitude 391DL

A family- and guest-oriented Solitude with a private rear bedroom/full bath and an upper loft, rather than a single-purpose entertainment room.

Solitude 391DL scale drawing: 42 ft 5 in long, 13 ft 5 in tall Side elevation drawn to scale from the published exterior length of 42 ft 5 in and exterior height of 13 ft 5 in. 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 2 ft 5 in longer than a 40 ft pad. 13 FT 6 IN CLEARANCE 13 ft 5 in 42 ft 5 in overall 40 FT PAD Roof: 1 in under a 13 ft 6 in limit Length: 2 ft 5 in longer than a 40 ft pad SCALE DRAWING FROM PUBLISHED DIMENSIONS

Drawn to scale from the published 42 ft 5 in length and 13 ft 5 in height, on a generic outline: 1 in under a 13 ft 6 in roof limit and 2 ft 5 in longer than a 40 ft pad.

Why the 391DL belongs on a different shortlist

The 391DL uses its rear section as a private guest bedroom with a full bathroom, then adds an upper loft above that area. This creates separate sleeping and bathroom access for guests instead of asking the primary lounge to double as the only overnight space.

Layout emphasis Guest bedroom, full bath, and loft
Length position 6 of 10 shortest
Dry-weight position 7 of 10 lightest

Who this floor plan fits

This floor plan fits extended families, traveling couples who host often, or owners who want a second private sleeping zone. It is the more residential guest arrangement when compared with the 388MBS workspace/guest room or the sofa-based sleeping available in entertainment-focused layouts.

Tradeoff to examine: The additional bedroom, bathroom, and loft make layout inspection essential: buyers should evaluate stair access, headroom, privacy, and how much of the coach remains available as shared living space. Its 42 ft 5 in length also places it firmly in the large-site category.

Weight implications for the 391DL

Using the year-specific figures in this record, the 391DL has 3,500 lb between its 15,500 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 3,100 lb pin weight equals about 20.0% 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 7 of 10 from lightest to heaviest and 6 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 106 gal

The recorded 106-gallon black-water capacity is double the 53 gallons shown for several single-bath siblings, which aligns with the page's guest-bath use case. Its 3,500-pound dry-to-GVWR difference sits near the middle of the 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.

391DL comparisons that change the decision

These siblings were selected by layout purpose and measurable tradeoffs, not only by nearest published length. The differences below use the year-specific records on RVBlueprints.

What to test during a 391DL walkthrough

  • Climb into the loft and test access, headroom, ventilation, guard protection, charging access, and the ease of changing bedding before assigning it to guests.
  • Close both bedroom and bathroom doors while other occupants use the kitchen to assess privacy, sound transfer, and nighttime movement through the trailer.
  • Confirm that each bathroom has the storage, counter space, and tank connections expected; two bathrooms add value only when both work for the household.
  • Compare the rear suite with the 388MBS mid room to decide whether a fixed guest bedroom is worth giving up a more flexible work-oriented space.
