The Honest Truth About Van Build Costs
Most "budget van build" videos on YouTube are sponsored by tool companies, panel companies, and mattress brands. Our numbers come from community members who tracked every receipt. No sponsorships, no inflated estimates, no hidden costs buried in fine print.
📌 Before You Budget The van (or bus) purchase is separate from the build cost. A used cargo van costs $8,000–$25,000. A school bus runs $5,000–$15,000. Add build costs on top of that.

Where to Save vs Where to Spend
Spend More On:
- Batteries — cheap AGM costs you more over 3 years than quality lithium
- Roof fan — you'll use it every single day; get a Maxxair not a $30 box fan
- Fridge — a quality 12V compressor fridge pays for itself in spoiled food averted
- Insulation — the one thing you cannot easily fix later
Save Money On:
- Flooring — vinyl plank looks great and costs 1/5 of hardwood
- Furniture hardware — IKEA and hardware stores beat van-specific retailers
- Water storage — food-grade containers work as well as $200 "vanlife" tanks
- Curtains and soft furnishings — thrift stores and fabric stores win here
