A market-backed price for your custom campervan — built on real comparable listings and AI analysis, not guesswork.
When it's time to sell a custom campervan, most owners have no idea what it's actually worth. The tools that exist either don't apply or actively mislead.
Kelley Blue Book prices the base vehicle. It has no concept of a $60,000 professional conversion sitting on top of a $40,000 chassis.
NADA covers mass-produced RVs. A one-of-a-kind DIY build with composting toilet and 400Ah lithium doesn't fit any of their categories.
A certified NADA-recognized appraisal takes a week and costs hundreds — before you've even listed the van. And they're still struggling with custom conversions.
Sellers routinely over- or underprice by $20,000–$40,000 because they anchor to what they spent. The market doesn't care what you paid — it cares what comparable builds actually sell for.
A 5-step questionnaire covers everything that affects what buyers actually pay. Most people finish in under 5 minutes.
Chassis make and model, wheelbase, drivetrain (2WD vs 4×4), year, mileage, and region. These are the biggest drivers of base value — a 2020 Sprinter 170 4×4 in the Mountain West commands a very different price than a 2015 ProMaster 136 in the Midwest.
Build type (professional shop, high-end DIY, standard DIY, or minimal), approximate build cost, and the features that carry real resale value. Not every feature matters equally — a diesel heater adds more value than a propane one; a 400Ah lithium bank adds more than a 50Ah AGM.
Extras that buyers notice and pay for — Starlink, awning, roof rack, swivel seats, MaxxAir fans, cell booster, notable brands (Victron, Battleborn, Webasto). You can also add free-text notes about anything unique to your build.
Layout type (fixed bed, convertible, Murphy, adventure, luxury) and interior condition (excellent / good / fair / poor). Honest condition ratings produce accurate prices — a "fair" build priced as "excellent" will sit on the market.
Email address (to receive your report) and why you're looking — selling, verifying a price before buying, or just curious. That's it.
After you submit, we run a three-layer analysis that takes about 20–30 seconds. Here's what happens under the hood.
We start with a formula-derived baseline: chassis base value (2023 reference prices for every major platform) × tiered depreciation × mileage adjustment + build recovery + feature premiums × aesthetic multiplier × regional demand multiplier. This gives the AI a quantitative anchor — not the final price, but a reasoned starting point the AI can agree with, push above, or pull below based on what the comps show.
We query our database of 2,700+ real listings across multiple marketplace sources, filtered to the past 9 months and priced $5,000–$200,000. Crucially, we don't filter by chassis make — a bare-bones Transit is more similar to a bare-bones Sprinter than to a $120K professional Transit build. Every listing is scored for similarity across year gap, mileage, feature overlap, build type match, region, and sold status (sold comps count 2× — they're confirmed market prices, not asking prices). We return the top 25–30 candidates.
GPT-4o receives your full specs, all 25–30 candidates, the formula baseline, and a guardrail range (75–125% of the comp weighted median). It selects the 10 most comparable listings with reasoning for each, determines fair market value within the guardrail, and produces per-comp appraisal notes, a valuation narrative, key strengths and concerns with estimated dollar impact, an ideal buyer profile, and ready-to-post listing copy. The AI reasons about build DNA, feature interactions, and market context in ways a formula cannot.
From the AI-determined fair market value, we calculate three prices: Quick Sale (~78% of FMV, moves in ~30 days), Fair Market (FMV, 60–90 days), and Premium (~115% of FMV, 90+ days or best offer). All prices are rounded to the nearest $500 — false precision doesn't help sellers.
Our comp pool is built from active and recently sold listings scraped from dedicated campervan marketplaces. We update regularly so prices reflect current market conditions, not 2-year-old data.
Dedicated campervan marketplace with structured listing data. High-quality photos and detailed build descriptions — one of the strongest comp sources for professional builds.
Large aggregator of campervan listings. Strong coverage of mid-market DIY builds and a wide regional footprint across the US and Canada.
We're continuously adding more marketplaces to improve comp pool depth, particularly for non-Sprinter platforms and regional markets.
Listings older than 9 months are excluded from comp scoring. Sold and removed listings count as confirmed sale prices — they carry twice the weight of active listings in our median calculation.
The three-tier price range is always free. The $29 report gives you the analysis behind the number — the data and reasoning you'd need to price and market your van with confidence.
