Montana High Country 300RK

The High Country with the lightest pin: 2,055 lb, only 16.4% of its 12,540 lb dry weight. Keystone builds it around a rear kitchen and, in its own tagline, an L-shaped sofa.

The outline is a generic fifth-wheel shape, not a profile of this unit. Roof sits 2 in under a 13 ft 6 in limit. Overall length is 5 ft 1 in shorter than a 40 ft pad. 13 FT 6 IN CLEARANCE 13 ft 4 in 34 ft 11 in overall 40 FT PAD Roof: 2 in under a 13 ft 6 in limit Length: 5 ft 1 in shorter than a 40 ft pad SCALE DRAWING FROM PUBLISHED DIMENSIONS

Drawn to scale from the published 34 ft 11 in length and 13 ft 4 in height, on a generic outline: 2 in under a 13 ft 6 in roof limit and 5 ft 1 in shorter than a 40 ft pad.

Rear kitchen and a 2,055 lb pin: the 300RK's pitch

If truck payload is the constraint, this is the High Country to shortlist. Its 2,055 lb hitch weight is 1 of 3 in the lineup, 200 lb under the shorter 290RL and 730 lb under the 391TB, and its 16.4% pin share is the lowest of the three. At 34 ft 11 in it still clears a 40-foot pad by 5 ft 1 in, and it carries the same 227 gal of tanks as the 290RL.

Keystone's tagline names the "Rear Kitchen" first and the "L-Shaped Sofa" last. On the drawing the sink sits under the rear window with a cabinet on each side, the range and microwave share the road-side slide with the sofa, and a peninsula with a pull-out trash can divides the kitchen from the living area. That same slide carries the L-shaped sofa and an end table, facing an entertainment center with fireplace and TV built against the bath wall. The door-side slide holds the 16 cu ft 12-volt refrigerator, a pantry, and a desk with pull-out dinette. Keystone lists a 65-inch TV for this plan where the other two High Country plans list a 50-inch set.

Two directions away from the 300RK's rear kitchen

Each sibling answers a different objection to this plan. Differences are arithmetic from the published figures.

If cargo capacity outranks pin weightMontana High Country 290RL

1 ft shorter and 265 lb lighter, with 820 lb more cargo capacity at 3,980 lb, the most in the family. The cost is 200 lb more on the pin. The living room moves to the rear wall with theater seating, and the kitchen becomes a center island.

Open record →If the rear of the trailer has to sleep a familyMontana High Country 391TB

9 ft longer, 3,325 lb heavier, and 730 lb more on the pin. Sleeping capacity rises from 4 to 9, with a rear bedroom, a bunk loft, and a second full bath where this plan has its kitchen, plus gray and black tanks of 150 gal and 100 gal. Cargo capacity is 240 lb lower.

What the 300RK gives up: 820 lb of cargo and the theater seating

A rear kitchen concentrates appliances behind the axles: here the range, microwave, sink, refrigerator, and pantry all sit in the rear half of the trailer. The low published pin weight fits that picture, but it comes with less cargo capacity than the lighter 290RL, 3,160 lb against 3,980 lb. Whatever goes into that rear pantry and those cabinets also rides behind the axles, so the empty-trailer pin figure is a starting point for the loaded one, not a forecast of it.

The seating is the other difference. Keystone's model-wide feature list names theater seating with electric recliners, but the 300RK drawing shows the L-shaped sofa in its place, and sleeping capacity is 4 with one king bed drawn.

300RK, rear window to front wardrobe

  1. At the rear sink, bring the road-side slide in. The range and microwave travel in that slide, so check what the peninsula and sink leave usable with it closed.
  2. Pull the dinette out from the desk in the door-side slide and open the refrigerator beside it. Refrigerator, pantry, and desk share one wall, and the option drawn below the plan is a larger 18 cu ft refrigerator in the same position.
  3. Sit at the far end of the L-shaped sofa and look at the entertainment center on the bath wall. Then ask the dealer which seating this unit has and which piece makes up into a bed, since the feature list and the drawing describe the living area differently.
  4. In the front bedroom, open the washer and dryer cabinet beside the wardrobe. Appliances there add weight ahead of the axles and eat into the 200 lb pin advantage this plan holds over the 290RL.

300RK sources and the one-number height

Weights, length, tanks, cargo capacity, and sleeping capacity come from Keystone's 2027 Montana High Country 300RK page, checked on 2026-08-21. The tagline, feature list, and 2027 drawing were read on 2026-09-26, and the table matched on that date. The 300RK carries Keystone's new-floor-plan label.

The roof figure is a single 13 ft 4 in exterior height that Keystone labels without separating the A/C. With a main and a bedroom air conditioner standard on the High Country, measure the unit itself before using routes near a 13 ft 6 in limit; the published number leaves 2 in.
