Why the 370DV belongs on a different shortlist
Grand Design presents the 370DV around two connected ideas: a trailer length below 40 feet and an open-concept living-room/kitchen space. That makes it the lineup's middle step for buyers who find the 310GK too compact but do not want to begin with a 41- to 43-foot floor plan.
Who this floor plan fits
The 370DV makes the most sense for shoppers who want the kitchen and lounge to function as one shared everyday zone. At 37 ft 10 in, it is 3 ft 6 in longer than the 310GK but still 3 ft 6 in shorter than the 380FL and 382WB.
Tradeoff to examine: Its open layout prioritizes a common living area rather than the separated front or rear entertainment rooms found in larger siblings. Buyers should decide whether that openness is more valuable than having a door or elevation change that creates a distinct second zone.
Specifications
Weight implications for the 370DV
Using the year-specific figures in this record, the 370DV has 5,200 lb between its 13,800 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 2,700 lb pin weight equals about 19.6% 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 2 of 10 from lightest to heaviest and 2 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
The recorded 83/106/53-gallon fresh, gray, and black capacities match the 310GK, 376RD, 382WB, and 388MBS. The 5,200-pound dry-to-GVWR difference is second only to the 310GK in this lineup, based on the year-specific figures used by RVBlueprints.
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.
370DV 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 370DV walkthrough
- Stand in the kitchen while another person uses the theater seating or dining area to test whether the open room supports simultaneous cooking and relaxing.
- Measure the intended campsite and storage space against 37 ft 10 in plus maneuvering room; being below 40 feet does not guarantee acceptance everywhere.
- Check refrigerator, pantry, bathroom, and bedroom access with the slides retracted, because an open layout at camp may change substantially in travel mode.
- Compare the 370DV's basement and interior storage directly with the 310GK; the extra length should solve a specific storage or circulation need.
Source note
The brochure states that listed exterior height excludes the second A/C.
