RV Floor Plans Explained: Bunkhouse, Rear Living, Front Kitchen and More

RV floor plans decide how a rig actually lives: where you sleep, cook, sit and store things matters more to long-term happiness than almost any other specification. Two trailers of identical length and price can feel completely different inside because the layout spends the space differently. This guide decodes the model-number codes manufacturers use to label layouts, walks through the main layout families, and shows how to match a plan to the way you actually travel.

How to Read a Floor Plan (and a Model Number)

Most RV model names carry the layout in code. A name like "2600RB" or "31BH" usually combines a number — roughly the living or box length in feet, though it rarely matches the true overall length — with letters describing the layout. The letters are the useful part, because they tell you the plan before you ever see a diagram.

There is no industry standard for these codes. Each manufacturer runs its own system, letters get reused with different meanings between brands, and a code that means "rear bath" at one maker may not exist at another. Treat the table below as the common vocabulary most large makers use, then confirm against the actual floor plan diagram on the listing — the diagram never lies, the badge sometimes does.

The Floor Plan Code Glossary

CodeMeaningWhat it tells you
BHBunkhouseDedicated bunk beds, usually at the rear — the family layout
BHSBunkhouse, with slideBunks plus a slide-out that widens the living or bunk space
RKRear kitchenGalley across the back wall; living space moves forward
RLRear livingSofas/theatre seating at the rear, often with a large back window
RERear entertainmentRear living variant built around an entertainment centre and TV
RBRear bathroomFull-width bathroom across the rear; bedroom moves forward
FBFront bedroom / front bathFront bedroom is the default on most plans; FB flags a front bath on some brands
FKFront kitchenGalley at the front, common on fifth wheels with an upper-deck twist
FLFront livingLiving room at the front (raised, on fifth wheels), bedroom at the rear
MBMid-bunkA small bunk room mid-coach, often convertible to an office
QD / QBQuad bunkFour bunks — two stacked pairs, usually in a rear bunk room
OKOutside kitchenAn exterior galley under an awning-side hatch, paired with an interior code
SSlide (suffix on some brands)The layout includes at least one slide-out

A few traps for the unwary: the length number is marketing, not measurement — a "28" can measure nearly 33 feet overall, which matters for campsite fit and storage, so always check the manufacturer's stated exterior length. And codes combine: a 290BHS is a bunkhouse with a slide, a 33RETS-style name stacks rear entertainment with other features, and toy haulers swap the letter logic for garage length (a "350" toy hauler name often encodes the garage or total length differently again).

The Main Layout Families

Bunkhouse (BH)

The family default. Bunks — two, three or four — sit in a rear room or alcove, giving children a door (or at least a curtain) of their own and keeping the main living area adult-shaped in the evening. The trade-offs: bunk space is borrowed from the bathroom or living room, and once the children outgrow the bunks the space converts awkwardly. Families comparing bunk plans should also read our roundup of the best RVs for families, where bunkhouse variants are compared by sleeping capacity.

Rear living (RL / RE)

The couples' favourite. Seating clusters at the back around big windows, the kitchen sits mid-coach, and the bedroom is a private front room. It is the layout that feels most like a small apartment and the best plan for long evenings inside — but it gives up the second sleeping zone, so guests mean converting a sofa.

Rear kitchen (RK)

Cooks love it: counter space runs the full width of the coach, and the plumbing concentrates at one end. The costs are a smaller living area and, on trailers, weight distribution worth checking — a heavy rear kitchen unloads the tongue, and tongue weight too far below 10–15% of trailer weight makes for nervous towing.

Front living and front kitchen (FL / FK)

Mostly fifth wheel territory. FL puts the lounge up the steps at the front — a raised, separated room that full-timers rate highly — with the bedroom at the rear. FK moves the galley forward instead, freeing the rear for living or bunks. Both plans spend their best space on the room they name; check the other rooms for the compromise.

Rear bath (RB) and mid-bunk (MB)

RB plans give you the biggest bathroom in the class — sometimes with dual sinks and a proper shower — at the price of a smaller bedroom or living area. MB is the modern hybrid: a small mid-coach room that works as bunks for children, an office for remote workers, or premium storage, and it has become the defining plan of the post-2020 market.

Slides: The Invisible Dimension

The floor plan diagram shows the rig with slides extended; your life at a rest stop, a tight site or a stormy travel day happens with them in. Before falling for a plan, check three things: whether you can reach the bathroom and fridge with slides closed, how much floor the slides actually add (a shallow dinette slide changes less than a full-depth sofa slide), and what the slide displaces — slides add weight, cost and one more sealing surface to maintain. Two shallow slides often live better than one huge one.

Matching the Plan to Your Travel Party

  • Couples: rear living or front living, a walk-around bed you can make without climbing over it, and a bathroom you do not have to cross the bedroom to reach at night.
  • Families: bunkhouse or mid-bunk, a second half-bath if the budget stretches, and an outside kitchen to keep breakfast chaos outdoors.
  • Full-timers and remote workers: a door that closes on a workspace (MB or a bunk room), residential-size fridge, and tank capacity over layout novelty.
  • Entertainers: rear living with seating facing each other, not just the TV.

Length and layout interact — a 30-foot rear-living trailer and a 30-foot bunkhouse tow identically but live completely differently. Our guide to what size RV to buy covers the length, weight and campground-fit side of the same decision.

Verify the Plan in Person

Diagrams flatter. Stand in the shower. Sit on the toilet with the door closed. Lie on the bed and check for knee room at the wardrobes. Open every cabinet with the slides in your travel configuration, and pace the kitchen triangle while someone sits at the dinette. Ten minutes of this finds more than an hour of brochure reading.

When you have a shortlist of layouts, browse current RV listings and filter your attention by plan, not just by year and price — the right floor plan in a rig one year older will make you happier than the wrong plan in a newer one.
