Budgetplanner voor bestelwagenconversie

The Van Conversion Budget Planner sums the base van purchase cost with the major conversion line items: insulation, electrical/inverter system, plumbing, solar panels and batteries, and interior buildout. Typical DIY van conversion ranges $15,000–$30,000 on top of the van itself, producing a total project cost of $40,000–$80,000 for a high-quality build. Professional conversions (Outside Van, Vandoit, Boho Camper Vans) charge $80,000–$200,000+ depending on customization. Base van options span a wide range: cargo van (used Transit / ProMaster / Sprinter $20–40k for 2018+), camper van conversion-ready ($30–50k for newer models), or used Class B RV ($50–100k for factory-built). Higher trim levels (4×4 AWD Sprinter) add $5–15k. New vans command 30–50% premium but offer warranty and reliability. Most DIY builders target a $25–40k base van and add $15–25k in conversion to hit the $40–65k total sweet spot. Conversion component costs: Insulation $800–2,000 (Havelock wool, Thinsulate, or rigid foam — better insulation prevents condensation in cold weather). Electrical $3,000–8,000 (lithium battery bank 200–400 Ah, MPPT charge controller, 2,000W inverter, breaker panel, outlets). Plumbing $1,000–3,000 (fresh water tank 20–40 gal, grey water tank, pump, sink, optional shower). Solar $2,500–5,000 (300–600W panels, MPPT controller, mounts). Interior $4,000–8,000 (cabinets, bed platform, swivel seats, flooring, walls). The build philosophy choice: 'stealth' van (looks like a regular cargo van, urban-friendly, fewer windows) vs 'overland' van (windows, roof rack, awning, exterior storage, designed for boondocking). Stealth builds save ~$3,000–5,000 by skipping exterior elements but limit comfort. Most full-time van lifers gravitate toward a hybrid — moderate stealth with good interior livability. Plan 200–500 hours of DIY labor over 3–6 months for an experienced builder; first-timers should budget 600–1,200 hours.

• !Underestimating electrical needs — most builders upgrade within first year
• !Skipping ventilation — leads to condensation, mold issues in cold climates
• !Overbuilding interior — adds weight, reduces fuel economy, harder to modify later
• !Forgetting hidden costs (registration, insurance, build supplies, tools)
• !Not budgeting for tow vehicle conversion (some folks switch to Toad after van life)
