Why the 417KB belongs on a different shortlist
The 417KB centers the rear of the coach on an expansive kitchen with a large island and walk-in pantry. Grand Design presents the kitchen and living room as one connected space, so the plan favors everyday cooking, storage, and conversation over a closed entertainment room.
Who this floor plan fits
This is the rear-kitchen shortlist choice for owners who prioritize pantry volume and an open social area. It should be compared directly with the 390RK, which is 9 inches longer and also uses a rear kitchen but carries different recorded tank and pin-weight figures.
Tradeoff to examine: The 417KB has the highest published pin weight among the standard 19,000-pound-GVWR Solitudes in this dataset at 3,290 pounds. That makes truck payload and rear-axle checks especially important even though the trailer is not the longest model in the lineup.
Specifications
Weight implications for the 417KB
Using the year-specific figures in this record, the 417KB 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 3,290 lb pin weight equals about 21.2% 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 5 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
Its recorded tanks are 83 gallons fresh, 106 gallons gray, and 106 gallons black. Compared with the 390RK, it gives up 44 gallons of gray capacity but records 6 additional gallons of black capacity.
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.
417KB 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 417KB walkthrough
- Load the walk-in pantry with a realistic grocery list and check shelf depth, door swing, ventilation, and whether heavy items can be secured for travel.
- Open the island, refrigerator, pantry, and adjacent seating at once to make sure the open-concept room still has comfortable working and passing clearance.
- Compare the rear kitchen directly with the 390RK, measuring counter length and storage instead of relying on both models' shared rear-kitchen label.
- Calculate truck payload with passengers, hitch, tools, and cargo before adding trailer pin weight; the 3,290-pound published figure is unloaded and already substantial.
Source note
The brochure states that listed exterior height excludes the second A/C.
