Insurance During the Van Build: What Covers You Before the Conversion Is Done

Your cargo van has an insurance blind spot between purchase and finished conversion. Here's what covers you during the build and how to close the gap.

The Van Guide

The moment between buying a cargo van and finishing the conversion is the period when most van builders have the least insurance protection and the most financial exposure. You have a vehicle worth $20,000 to $50,000 sitting in a driveway or shop, you are installing $30,000 to $80,000 in components and materials inside it, and the insurance you are carrying was probably written for a cargo van that no longer exists in its original form.

This is the article nobody writes, because it sits in the gap between two product categories. Auto insurance covers the vehicle you bought. RV insurance covers the vehicle you are building. Neither one clearly covers what you have right now — a partially converted van with tens of thousands of dollars in components bolted inside it that the insurer does not know about.

Here is what actually covers you during the build, where the gaps are, and what to do about them.

The Three Phases of Van Build Insurance

Think of the build process as three insurance phases, each with different coverage realities:

Phase 1: You Own a Cargo Van (Before Any Work Starts)

At this point you have a standard vehicle. Your auto or commercial insurance covers it the way it covers any other vehicle — collision, comprehensive, liability, the usual. The insured value is the cargo van’s market value. This is clean and simple.

What’s covered: Theft, fire, weather, collision, liability while driving. What’s not covered: Nothing unusual — this is standard auto insurance on a standard vehicle.

A critical warning: Do not call your insurer to tell them you plan to convert the van. Multiple owner reports confirm that some carriers treat stated conversion intent as a material change in use and will non-renew the policy. On The Wandering Woods blog, an owner reported that Progressive dropped them after learning about the planned conversion. On multiple forum threads, owners report that GEICO specifically drops policyholders who disclose conversion intent — before any work has begun. The carrier’s logic is that a planned conversion changes the risk profile of the vehicle, even while it is still stock. Wait until you have actually started the build and are ready to discuss coverage options before contacting your insurer about the conversion.

Phase 2: You’re Mid-Build (Conversion in Progress)

This is where the gap opens. You have started installing components — maybe you have done insulation, framing, electrical rough-in, a bed platform, some cabinetry. The van is no longer a stock cargo van, but it is not yet a finished campervan.

What your existing auto policy covers: The base vehicle, to its pre-conversion market value. Liability while driving. Comprehensive perils (theft, fire, weather) to the vehicle shell.

What your existing auto policy probably does not cover: The conversion work. The components installed. The materials stored inside. If the van catches fire in the driveway and the interior is destroyed, a standard auto policy pays to repair or replace the cargo van. It does not pay to replace the $15,000 in batteries, wiring, solar panels, cabinetry, and appliances that burned with it.

The legal nuance: Whether installed components are covered depends on the specific policy language and the state. Some auto policies cover “permanently attached equipment” up to a certain value. Some explicitly exclude aftermarket modifications above a threshold. Some are silent on the question, which means the adjuster decides at claim time — and “the adjuster decides” is not a coverage plan.

The practical risk: Most DIY builders carry the most financial exposure during the build phase. You have spent money on the van, spent money on components, and spent money on tools — but the insurance you are carrying was designed for a $25,000 cargo van, not a $60,000 work in progress.

Phase 3: Build Is Complete, Retitled as RV

At this point you can (and should) bind a Class B RV policy that covers the complete vehicle — chassis plus conversion — at its full value. See How to Insure a DIY Van Conversion for the step-by-step process. The gap closes.

What You Can Do During Phase 2

There is no single clean product that perfectly covers a partially built van conversion. But there are several approaches that narrow the gap, and the right combination depends on your build value and risk tolerance.

Option 1: Notify Your Current Auto Insurer (Carefully)

Call your existing auto or commercial insurer and tell them you are converting the van. Ask two specific questions:

  1. “Does my current policy cover aftermarket modifications and permanently installed equipment, and if so, up to what value?” Some policies cover modifications up to a stated limit (often $1,000 to $5,000). Some cover them at actual cash value. Some exclude them entirely. Knowing the answer tells you how big the gap is.

  2. “Do I need to notify you of changes to the vehicle, and will disclosing the conversion affect my coverage or premium?” Some carriers want to know about vehicle modifications and will adjust the policy. Others will decline to cover a vehicle that has been significantly modified. Either answer is useful — if the carrier declines, you know to shop for alternatives before a loss happens.

Important: This step carries a real risk. As noted in Phase 1, some carriers will non-renew your policy when they learn about the conversion. If you are currently with GEICO, Progressive, or another carrier that is known to drop van converters, consider shopping for a conversion-friendly carrier first — State Farm and some regional carriers are more willing to work with mid-build vehicles. Do not assume your current policy covers the conversion just because the carrier does not cancel you. Silence from an insurer is not the same as coverage. Get the answer in writing if possible.

Option 2: Increase Coverage on Your Auto Policy

If your insurer will work with you, ask about increasing the stated value or adding a rider for custom equipment. Some carriers offer “custom equipment” or “aftermarket parts” endorsements that extend coverage to permanently installed modifications up to a scheduled value. This is the simplest way to narrow the gap — it is not a perfect solution, but it is far better than carrying a policy that only covers the cargo van shell.

Progressive includes $1,000 in Custom Parts and Equipment (CPE) coverage by default on its auto policies, upgradable to $5,000. That is better than nothing but inadequate for most van builds — $5,000 covers perhaps the electrical system and nothing else. State Farm’s “Customization Report: Panel or Van Body Type Vehicles” form can add substantially more coverage, but availability depends on the agent.

The premium increase for a custom equipment endorsement is typically modest — often $50 to $200 per year depending on the value added. Compare that to the risk of an uninsured $30,000+ loss and the math is straightforward.

Option 3: Scheduled Personal Property Coverage

Some homeowner’s or renter’s insurance policies will cover personal property anywhere — including inside a vehicle. If you have a homeowner’s or renter’s policy with adequate personal property limits, the components and materials inside the van during the build may be covered under that policy as personal belongings, up to the policy’s per-item and per-occurrence limits.

This is not a substitute for vehicle insurance. It covers your stuff, not the vehicle. But it can fill a meaningful portion of the gap — if the van is broken into and your $3,000 in batteries and $2,000 in solar panels are stolen, a homeowner’s policy with adequate personal property coverage may pay the claim even if your auto policy does not.

Check the specific policy language. Some homeowner’s policies exclude items that have been permanently installed in a vehicle. Some have sub-limits for certain categories (electronics, tools). Some require items over a certain value to be individually scheduled.

Option 4: Inland Marine or Builder’s Risk Insurance

For high-value builds — especially if you are building in a rented shop or on someone else’s property — inland marine insurance or a builder’s risk policy may be worth exploring. These are commercial insurance products designed to cover property that is in transit, being modified, or under construction.

Inland marine policies cover materials, components, and work in progress at their stated value. The coverage follows the property, not the location — meaning components are covered at your shop, in your driveway, or in transit from a supplier.

These policies are typically written through a commercial insurance broker, not a personal auto carrier. Premiums vary widely depending on the values insured, the location, and the builder’s profile. For a DIY build with $30,000 to $50,000 in components and materials, expect to pay $300 to $800 for a policy term covering the build duration.

This is the most comprehensive option but also the most complicated and expensive. It makes the most sense for builds with total component value exceeding $30,000, builds happening in a shared or rented space, or situations where the builder’s homeowner’s policy does not adequately cover personal property.

Option 5: Expedite the Build and Retitle Early

The pragmatic option that most builders overlook: finish the build to the point where it meets the carrier’s habitation requirements, retitle, and bind a Class B RV policy as soon as possible.

The build does not need to be cosmetically finished to qualify. Progressive requires cooking, sleeping, refrigeration, HVAC, a drinkable water supply, and electrical. If those six systems are installed and functional — even if the cabinetry is not trimmed out and the walls are not paneled — the van may qualify for retitling and RV insurance coverage.

Getting a Class B policy in place as early as possible, even if the build is still in progress cosmetically, closes the biggest insurance gap. You can continue finishing the interior under the protection of an RV policy that covers the full conversion value.

A caution: do not bind an RV policy and then disclose to the carrier that the van is not yet a functioning campervan. The policy requires the vehicle to be what the application says it is. If you retitle and bind coverage, the habitation systems need to be installed and working at that point.

What Professional Builders Carry (and Why It Matters to You)

If you hired a professional van builder, their shop should carry insurance that covers the van during the build. The relevant policies are:

  • Garage keeper’s insurance: Covers customer vehicles in the shop’s care, custody, and control. If your van is damaged by fire, theft, or collision while at the builder’s facility, garage keeper’s coverage is what pays.
  • General liability: Covers third-party injury and property damage. If a visitor to the shop trips over your van’s extension cord, this is what covers it.
  • Inland marine / builder’s risk: Some builders carry this to cover materials and work in progress.

Ask your builder whether they carry garage keeper’s insurance and what the limits are. If the builder does not carry it (or carries inadequate limits), your van is protected only by your own auto policy while at the shop — which, as described above, probably does not cover the conversion work.

This is a legitimate question to ask during the builder selection process. A builder who carries proper insurance is protecting both your asset and their business. A builder who does not carry insurance is asking you to absorb a risk that should be shared.

The Coverage Gap Nobody Warns You About

The most dangerous moment in the build process is not when the van is empty or when it is done. It is the two to four months in the middle when the most expensive components are installed but the van is not yet retitled and insured as an RV.

A typical scenario: you have a $30,000 cargo van with $25,000 in installed components (batteries, solar, inverter, cooktop, fridge, cabinetry, plumbing). Your auto policy covers the van for $30,000. Your homeowner’s policy may cover some of the components up to its sub-limits. But the total exposure — $55,000 or more — is not fully covered by either policy.

If the van catches fire, is stolen, or is totaled in an accident during this period, you face a gap that can run $10,000 to $40,000 or more.

The fix is a combination of the options above: notify your auto insurer, add a custom equipment endorsement if available, verify your homeowner’s personal property coverage, and close the gap as soon as possible by finishing the build, retitling, and binding a proper Class B RV policy.

Why No Carrier Has Solved This

In the UK, at least one carrier (Adrian Flux) offers a “camper in conversion” insurance product designed specifically for vehicles being converted. No equivalent product exists in the US market. No major US carrier, insurance industry group, or state insurance department has published guidance on insuring vehicles that are actively being modified from one use class to another.

The result is that every van builder navigates this gap individually, using some combination of the approaches above. Most builders, if they are honest about it, carry standard auto insurance during the build and hope nothing happens. On EXPLORIST.life, one builder explicitly described this as a calculated risk — acknowledging that the build was not fully covered during the conversion period.

That is not a plan. But it is the reality of the current market. Until a US carrier builds a product for this specific scenario, the approaches in this article are the best available options.

Coverage details reflect published carrier materials as of April 2026. Insurance products for vehicles under modification vary significantly by carrier, state, and policy type. Discuss your specific situation with your insurer before relying on any coverage assumption.

The GEICO non-renewal pattern is based on consistent owner reports across multiple forums (Sprinter-Source, Ford Transit USA Forum, Reddit r/vandwellers). GEICO does not publish a policy on conversion-related non-renewals. The UK “camper in conversion” product reference is based on Adrian Flux’s published product offering, which is not available to US-based vehicle owners.
