RV and Van Interior Remodeling

What you can move and what is holding the roof up

In a laminated sidewall coach, the aluminum stud cage is structural and so are certain interior partitions, particularly those flanking a slide opening or carrying a roof truss bearing point. Removing one because it makes the floorplan better is how you end up with a roof that sags at the centerline and a slide that binds within a season. We identify load paths before demolition, and where a wall genuinely must come out, we replace its function with a header or a beam rather than hoping the roof was overbuilt.

Stick and tin construction behaves differently. The framing is dimensional lumber, easier to modify and easier to misread, because a stud wall in an older trailer may be carrying nothing at all or may be the only thing keeping the roof bow from spreading. On a steel unibody van, the ribs and roof bows are the structure and the walls are trim, which makes layout changes freer but makes any cutting into the shell a much more serious decision.

Slides constrain everything. A slide room sweeps a fixed volume through the living space, and any new cabinet, seat base, or appliance that intrudes into that path will be discovered by the mechanism rather than by the designer. We map the full travel and the clearance envelope on the drawing, not with a tape measure after the boxes are built. The same goes for the underfloor: adding a floor-mounted item over the slide rails or the tank straps is a fast way to create a problem you have to undo.

Weight, balance, and the numbers on the sticker

Every unit carries a federal label listing gross vehicle weight rating and, on multi-axle units, gross axle weight ratings. Cargo carrying capacity is what remains after the unit as built, with full propane and a driver allowance, is subtracted. Many production trailers leave the factory with far less of that margin than owners assume, sometimes under a thousand pounds. Quartz countertops, a residential refrigerator, tile, and a lithium bank can consume all of it before a single suitcase goes in.

Placement matters as much as total mass. Weight added behind the rear axle on a travel trailer reduces tongue weight and moves the combination toward instability at highway speed, which is a genuine safety issue rather than a comfort one. Weight added high raises the center of gravity and makes crosswind handling worse. We plan heavy items low and between the axles wherever the layout allows it, and we tell you when a request pushes the numbers the wrong way.

The honest way to handle this is with a scale. On any remodel that adds meaningful mass we recommend weighing the unit by axle before and after, so the change is documented rather than estimated. It also settles arguments about whether a unit was already over its rating before we touched it, which is more common than the industry likes to admit. Substituting a solid surface countertop for stone, or a lighter frame for a sofa, often recovers hundreds of pounds with no visible compromise.

Materials selection follows from all of this. Baltic birch plywood in a cabinet box weighs less than particle core, holds a fastener far better, and survives humidity swings without swelling. Aluminum framing for a bed platform costs more up front and saves weight where it matters. These are not luxury choices, they are how a build stays inside the rating and stays together over rough pavement.

Surfaces, upholstery, and finishes that survive travel

Factory interior walls are usually thin luan panels with a printed vinyl film bonded to them. That film does not take paint without preparation, and the standard failure is a beautiful painted interior that starts peeling at the seams within a year. Adhesion requires degreasing, scuff sanding, and a bonding primer suited to vinyl, and even then the panel joints and battens need to be handled deliberately. We would rather replace a panel than paint over a surface that will not hold.

Upholstery in a vehicle is not living room upholstery. Foam has to resist compression set from being folded into a dinette, fabric has to hold up to abrasion and sunlight through large windows, and anything on a convertible mechanism has to tolerate being bent thousands of times. We specify contract-grade textiles with real abrasion ratings and marine vinyls where moisture is a factor, and we build seat bases so the mechanism is still serviceable after the new cover is on.

Window treatments, backsplashes, and trim are where road vibration shows up first. Adhesive-only backsplash tile fails at the edges, unsupported floating shelves rack and loosen, and trim held by pins alone works loose. Mechanical fastening plus adhesive is the standard here, edges get a captured trim rather than a caulk line, and anything with mass gets blocking behind it. It costs slightly more labor and it is the difference between a finish that lasts and one that rattles.

Electrical, plumbing, and the systems behind the walls

A remodel is the least expensive moment in a vehicle life to fix the wiring, because the walls are already open. Adding USB points, reading lights, a television location, or an induction cooktop means new circuits, and those have to be calculated against the existing panel capacity rather than tapped off whatever is nearest. We run new home runs, fuse at the correct rating, use marine-grade tinned conductor where corrosion is a risk, and label the panel so the next person can follow it.

The same window applies to plumbing. Aging supply lines, a marginal pump location, and a tank vent that was never routed properly are all cheap to correct while a floor is open and expensive to reach afterward. We look at what is exposed during demolition and give you a short list of things worth doing while access is essentially at no additional labor cost, separated clearly from the work you actually asked for.

Van conversions carry an extra layer, because seating and sleeping surfaces occupied during travel involve occupant restraint. Seat bases have to be anchored into structure with the correct backing, not into a plywood floor, and swivel bases and belted benches need to be installed to the manufacturer instructions to mean anything. We build to that standard and we will decline a request that puts a belt on something that cannot carry the load, which comes up more often than it should.

What is included

Layout drawing with clearance mapping

Slide travel, door swings, and mechanism envelopes drawn before demolition rather than discovered after.

Structural review and header work

Load paths identified, and any removed partition replaced with a beam or header that carries its function.

Weight planning and axle scaling

Material choices worked against cargo capacity, with before and after axle weights on substantial builds.

Cabinetry built for road service

Baltic birch boxes, mechanical fastening into structure, and hardware rated for vibration rather than residential use.

Contract-grade upholstery and surfaces

Textiles with real abrasion ratings, marine vinyl where moisture reaches, and captured trim edges instead of caulk.

Circuit additions and labeling

New home runs sized and fused to panel capacity, tinned conductor where corrosion is a risk, panel legend updated.

Signs you need this work

• A floorplan that wastes half the space on a dinette nobody eats at
• Cabinet doors and drawers that have been rattling loose since the unit was new
• Painted interior walls that are peeling at the panel seams
• Upholstery foam that has flattened where the dinette folds
• A layout that cannot accommodate a work surface or a permanent bed
• Wiring added over the years with no labeling and no obvious fusing
