Camper Van Layout: Wheel Wells, Doors and Usable Space

A van layout needs more than a rectangle for the cargo floor. Wheel wells occupy space, the walls change shape with height, and furniture needs room to open. Measure those constraints in your own van before deciding where the bed, cabinets and storage will go.

This guide focuses on the space you can use in daily life. Keep the free measurement worksheet (CSV) beside you, then use the SketchUp layout guide to compare your options.

Start with One Reference and One Unit

Record the vehicle's model year, wheelbase, body length and roof configuration. Choose one working unit and a clear reference for your measurements, such as the rear threshold. A note saying “wheel well starts here” is less useful than a measurement tied to a point you can find again.

Sketch a top view and a side view. Label the front, rear, driver side and passenger side. Write down where each measurement was taken; a width at the floor is a different entry from a width at the planned bed height. Mark a value as unverified when you still need to check it.

Record Each Wheel Well Separately

Measure each wheel well's length, height and projection into the cargo area. Record its position from your chosen reference. Also measure the space between the wheel wells and the widths where nearby furniture will sit.

Include the space taken by any planned enclosure, insulation or trim as a separate assumption. Keeping the bare feature and its planned covering separate lets you change the finish without losing the original measurement.

Check Door Openings and the Route Inside

Measure the actual opening you will use, including the point where trim or a threshold narrows it. Check the opening at the height of the object you plan to move through it. Then consider the route from the door to its final position.

A cabinet may fit in the cargo area once installed but be awkward to bring through a door as one assembled unit. Include that delivery and assembly question while the layout is still easy to change. Note where a bed or cabinet would obstruct the side entrance, rear access or a door handle.

Draw Furniture Open as Well as Closed

Start with the outside dimensions of the furniture, then add the space used by drawers, doors, lids and any bed-conversion movements. Check the position you will actually stand or sit in while using them.

• Can you reach a drawer handle with the bed in its normal position?
• When the drawer is open, can you reach what is inside?
• Can a cabinet door open without meeting another fixture?
• Can you perform each step of a convertible bed without first moving something else?
• Can you reach equipment that will need inspection or maintenance?

Use the exact equipment documentation for installation and service clearances. A furniture layout does not determine structural attachment points or equipment installation requirements.

Compare Two Arrangements Without Changing the Van

For example, compare a lower bed arrangement that places storage between the wheel wells with a raised arrangement that uses space above them. These are planning alternatives.

Keep the measured shell, wheel wells and intended mattress dimensions identical in both versions. Compare the resulting sitting room, storage access and entrance route. If a dimension is still uncertain, record it rather than adjusting the van model until the furniture appears to fit.

In SketchUp, keep furniture and van geometry in separate groups so you can move the fixtures independently. Use the official grouping instructions and check important distances with the Tape Measure tool. Model measurements help check the design; they still need to agree with the vehicle you measured.

Model Separate Storage Zones Around a Wheel Well

A cabinet's outside box is not the same as its usable storage. The wheel-well enclosure, cabinet panels, framing and hardware can occupy part of that box. For an early SketchUp check, represent the obstruction and the candidate storage spaces separately before deciding what belongs inside.

1. Keep The Obstruction Fixed: Use your recorded wheel-well position and planned covering to define the space that storage must avoid. Keep the bare wheel well and the planned covering identifiable, counting each finish allowance once. Do not resize the obstruction to accommodate a container.
2. Divide The Candidate Space: Consider separate zones ahead of, behind, inboard of and above the enclosure. Not every zone will exist in your layout. A broad cabinet footprint can span several zones while leaving less room for one continuous drawer or container.
3. Draw Each Zone Independently: Create a separate group for each candidate zone using the official grouping workflow. Within its editing context, use Rectangle with your planned dimensions, then Push/Pull to represent the height. Name the groups by location, such as “Storage Ahead Of Wheel Well” and “Storage Above Enclosure.” These boxes represent candidate empty space, not finished cabinet parts.
4. Check The Item Inside The Zone: Compare the actual container's maximum outside dimensions, including its rim, lid and handles, with the proposed internal space. Keep panel, frame and hardware allowances outside that empty-space envelope. If those details are undecided, label the zone provisional rather than treating the cabinet's outside dimensions as storage capacity.
5. Inspect From More Than One Direction: Use SketchUp's model views and Orbit tool to inspect the zone relative to the enclosure from above and from the side. Measure relevant distances. Keep this fit check distinct from the opening and access checks.

Record the Storage Zone and Its Assumptions

For each zone, note its name, model revision, supporting measurements, finish assumptions and intended contents in the measurement worksheet (CSV). Record separately whether the item fits inside the modeled space and whether it can pass through the planned opening. A container can meet one check while failing the other.

For a hypothetical storage bin above an enclosure, check both the available height and the opening used to insert the bin. Use the main blockout workflow for the drawing steps, then continue to the physical check below.

Check How Storage Will Come Back Out

A storage module can fit its parking space and still be difficult to remove later. Check the route out while the layout is easy to change. This exercise adds a removal check to the storage-zone model.

1. Name What Must Come Out: Choose one item, such as an empty storage bin or a removable furniture module. Record its maximum outside size, including handles, rims and any hardware that stays attached. State whether you are checking the bin alone or the whole module. These are different objects and may need different routes.
2. Keep A Starting Revision: Save an identifiable working copy using the recoverable-layout workflow. Keep the van shell, finishes and neighboring furniture at their recorded sizes. Represent the item as a separate group using SketchUp's grouping instructions, so selecting it does not select surrounding loose geometry.
3. Rehearse The Route In Stages: Select the whole group, activate Move, choose a reference point and move it toward the intended opening. SketchUp's Move instructions explain reference points, axis inference and entering a precise distance. Use your own measured values. Inspect intermediate positions as well as the final position; moving directly to an empty destination does not check the space crossed along the way.
4. Find The Limiting Opening: Compare the item's outside size with the route at the relevant height, including trim, handles and nearby fixtures. Use the Tape Measure tool to check distances between identified points. If the route appears to need tilting or turning, record that as a separate maneuver to investigate.

Record the Obstruction Before Changing the Layout

For a hypothetical bin below a bed, the bin might fit its storage zone but meet the bed frame before it reaches the door. Record that conflict and compare a revised opening or arrangement. Do not shrink the bin, wheel well or bed frame merely to clear the drawing.

Use the existing full-size mockup checklist to record physical access observations and the equipment’s service and removal requirements.

Test the Important Footprints in the Van

Use a simple physical mockup to test the bed and cabinet footprints before committing to materials. Include the wheel-well coverings and the space needed by moving parts. Walk through the actions you expect to repeat: entering, getting into bed, opening storage and reaching a frequently used item.

Write the result as a decision: “Drawer access needs revising in Layout A,” for example. Update the worksheet and save the next model revision. Recheck important measurements and openings before ordering materials or cutting panels.
