At Crescent Moon Vans, custom campervan conversions typically range from $45,000 to $75,000, while shell builds start at $20,000. These prices cover conversion work only; the van itself is a separate cost. We also offer free help sourcing new or used vans through local dealership partners.
Here is how the two approaches differ and what to consider before starting your build.
Full Conversion or Shell Build: Comparing the Starting Points
| Build approach | Published conversion pricing | Who it may suit |
|---|---|---|
| Custom campervan conversion | Typically $45,000–$75,000, excluding the vehicle | Owners who want the interior designed and built around their travel plans |
| Shell build | Starting at $20,000, excluding the vehicle | Owners who want help with the underlying systems and plan to finish more of the interior themselves |
The right choice depends on more than the initial budget. Consider your available time, practical skills, and how much work you want to take on before the van fits your needs.
What Goes Into a Custom Campervan Conversion?
A full custom conversion begins with the way you plan to use the van. Someone carrying bikes and outdoor gear may need storage beneath a fixed bed. Someone working while traveling may put more emphasis on a comfortable seating area, workspace, and electrical needs.
From there, the layout brings together sleeping space, cabinetry, storage, and the systems selected for the project. Available options include cooking areas, water systems, indoor showers, heating, ventilation, and off-grid power. The combination is planned for each build; every van does not need every feature.
Our custom campervan conversions are built in Cayce, near Columbia, South Carolina. The portfolio shows completed customer projects and gives you examples to discuss during a consultation.
What Is a Shell Build?
A shell build offers a different starting point for someone who wants to finish their own campervan interior. Our shell work focuses on insulation, electrical, ventilation, lighting, and hookups, leaving room for the owner to continue the interior at their own pace.
That can be useful if you are comfortable building furniture or storage but want professional help with the systems underneath it. Before choosing this route, discuss exactly which tasks the workshop will complete and what you will take on afterward.

What Affects the Cost of a Van Conversion?
Van size and conversion complexity help shape the amount of work involved. Layout, materials, cabinetry, and selected equipment also affect the project. A simple interior and a build with an indoor shower, extensive storage, and several electrical systems require different planning and installation work.
It helps to separate your requirements from your preferences. Start with the number of people traveling, sleeping arrangements, essential equipment, and the gear you need to carry. Then consider finishes and additional features within that plan.
Specific examples make those conversations easier. Our campervan project featuring LED lighting, painted cabinetry, and exterior underglow shows how individual finish and lighting choices come together in a completed interior. It is a design reference, rather than an itemized pricing example.
Remember to Budget for the Vehicle
The published conversion prices do not include buying the van. If you already own one, bring its make, model, year, and wheelbase to the conversation. If you are still shopping, talk through the intended layout before committing to a vehicle.
We can help source both new and used vans through local dealership partners. Keeping the vehicle purchase and conversion budget separate makes the overall plan easier to understand.
Start With Your Priorities
You do not need a finished floorplan to start a conversation. Bring your budget, a few reference photos, and a list of what you need the van to do. Tell us which decisions are settled and where you would like advice.
