Most van conversion tool lists exist to generate affiliate revenue, not to give you honest guidance. They pad out 10–15 items with things you probably own, things you can easily borrow, and things that appear in build videos but never appear in most real builds.
This is a different kind of list. It starts with what you actually need to own, explains why each item earns a buy rather than a borrow, and is honest about what to skip until you have proven you need it.
The Tool Trap#
Search “van conversion tool list” and you will find the same items repeated across dozens of sites: drill, circular saw, jigsaw, angle grinder, oscillating tool, orbital sander, router, miter saw, heat gun, torque wrench, rivet gun, crimper, multimeter, and more.
Some of those items belong on a buy list. Most belong on a borrow list. A few are irrelevant to most builds entirely.
The distinction matters because tools add up fast. Buying a full list before starting the build wastes $500–800 on things you use once or not at all. Buying strategically — owning what you use repeatedly, borrowing or renting what you use once — keeps tool costs to $200–400 for a complete basic kit. Estimate
What to Buy: Tools That Earn It#
These four belong on every buy list because they are used across every stage of the build, they cannot safely be borrowed (electrical tools) or produce worse results when cheap (drill).
Cordless Drill/Driver#
Used for pilot holes, screw driving, cabinet installation, bed frame assembly, and dozens of other tasks across every phase of the build. You will use this tool more than any other.
Why buy rather than borrow: You need it constantly throughout the build, not just for one session. Borrowing a drill for an afternoon is practical; borrowing it for three months of intermittent use is not.
Minimum quality threshold: An 18V or 20V brushless motor drill with at least two batteries. Brushless motors are meaningfully more durable and efficient than brushed, and the price difference is worth it for a tool you will use this heavily.
What goes wrong without it: Nothing in the build happens without this tool.
Jigsaw#
Used for curved cuts, wheel well fit-outs, cutting holes for fan installations, and any interior trim cuts that are not straight lines. A jigsaw handles the work that a circular saw cannot.
Why buy rather than borrow: You need it at multiple stages — when cutting insulation panels, when fitting around wheel wells, when cutting the roof for a fan, and when trimming any custom shape. Borrowing means waiting for availability at the moments you need it.
Minimum quality threshold: Any 4–6 amp jigsaw with variable speed accepts standard T-shank blades. Buy extra blades — you go through more than you expect.
What goes wrong without it: Your cuts become straight or nothing. Curved surfaces (wheel wells, irregular wall areas) require this tool.
Wire Crimper and Stripper#
The electrical tools are the ones that cannot be borrowed. Here is why.
A crimper creates a mechanically secure, gas-tight connection between wire and terminal. A solder joint done incorrectly is weaker than a good crimp. A crimp done with the wrong tool — the wrong die size for the terminal, improper seating of the terminal — is weaker than nothing.
Bad electrical connections cause heat, voltage drop, and fire. In a structure you sleep in. This is not a hypothetical risk.
Why buy rather than borrow: You need to crimp every connection as you make it. Electrical work is not a one-session task — connections get made, tested, adjusted, and remade across weeks of build time. Borrowing a crimper for an afternoon and returning it before you have finished wiring creates pressure to rush electrical connections, which is exactly the wrong approach.
Minimum quality threshold: A ratcheting crimper with the correct dies for your terminal sizes (ring terminals for battery connections use different die sizes than open barrel butt connectors). Do not buy a hardware store non-ratcheting crimper — the ratchet mechanism ensures a fully seated crimp every time.
The stripper: any decent adjustable wire stripper. The $12 version works fine.
Multimeter#
The other electrical tool that cannot be borrowed.
A multimeter lets you verify voltage, test continuity, and diagnose problems as you build. The alternative is working blind — making connections, hoping they work, and having no way to trace problems when they do not.
Why buy rather than borrow: Electrical troubleshooting is not a scheduled event — it happens whenever something behaves unexpectedly. That could be at 10 p.m. when you discover your charge controller is not reading the solar panels correctly. If your multimeter is at someone else’s house, you are stuck.
Minimum quality threshold: Any auto-ranging multimeter reads voltage, continuity, and resistance correctly. A $15–25 unit from a hardware store does everything a van builder needs.
What goes wrong without it: You cannot verify connections. You cannot diagnose problems. You are guessing.
What to Borrow or Rent#
These tools matter, but the math does not support buying them for a single build.
Circular saw: One-time use for cutting your plywood subfloor and bed platform. Rent from a tool rental shop for $25–40 per day, or borrow from anyone who has one. Estimate Most hardware stores will also cut sheet goods for a small fee — worth considering before buying or renting.
Miter saw: Useful for making precise angle cuts in trim, ceiling slats, or wood framing if you go that direction. Most builds have a handful of miter cuts, not hundreds. Borrow it for a weekend session when you know exactly what you are cutting. Buying a compound miter saw for one build does not make economic sense.
Router: Used for edge profiles, dado cuts, and decorative edges. Many builds use zero router work. If yours does, rent or borrow.
Orbital sander: Finishing tool. Useful if you are building wood furniture with exposed surfaces. Borrow for the finishing phase.
Heat gun: Useful for vinyl wrap, shrink tubing, and fitting plastic trim. Most van builds use it for 30 minutes total. Borrow.
What to Skip Entirely#
Angle grinder: It appears in build videos because professional fabricators and Sprinter custom builders use them for metal work. If your build involves custom metal fabrication — cutting steel frame, welding brackets — you need one. If your build is insulation, plywood, and wood furniture, you will not touch one.
Oscillating multi-tool: Useful for cutting in tight spaces when you need a jigsaw cut you cannot make with a jigsaw. Nice to have. Rarely actually needed in a van build. Borrow if you discover you need it.
Table saw: For dimensioning lumber. Rent from a makerspace for an afternoon if you need to rip large quantities of wood. Most van builds use precut lumber sizes that do not require a table saw.
Rivet gun: For pop rivets in metal applications. Some builds use them; most do not. Borrow if you discover a specific application.
The Electrical Tools Cannot Be Compromised#
It is worth repeating clearly: the crimper and multimeter are the tools where quality and ownership matter most for safety reasons.
Underbuilt electrical connections in a living space are a fire risk. The tools that make correct connections — and the ability to verify those connections — are worth buying and owning even if you own nothing else.
Budget $30–50 for a quality ratcheting crimper and $15–25 for a multimeter. That $45–75 investment protects everything else in the build.
Realistic Starter Toolkit Cost#
If you start from nothing and buy only what belongs on the buy list:
| Tool | Estimated Cost |
|---|---|
| Cordless drill/driver (18–20V, brushless, 2 batteries) | $80–150 |
| Jigsaw | $40–70 |
| Ratcheting wire crimper | $20–40 |
| Wire strippers | $10–15 |
| Multimeter | $15–25 |
| Drill bits, jigsaw blades, screwdriver bits | $30–50 |
| Total | $195–350 Estimate |
Renting a circular saw for sheet goods cuts: $25–40. Borrowing a miter saw for finish cuts: $0.
Full build tool cost: $220–390 Estimate
For a build that takes three to six months and produces a living space you use for years, that tool investment is among the best value decisions in the project.

Frequently Asked Questions
- What tools do I actually need for a van conversion?
- The essential buy list is short: a cordless drill/driver (18–20V brushless), a jigsaw, a ratcheting wire crimper, a wire stripper, and a multimeter. Everything else can be borrowed or rented for specific tasks. Total cost for this core kit is $195–350 (Estimate).
- Do I need a miter saw for a van build?
- Probably not. A miter saw is useful for precise angle cuts in finish trim and wood framing, but most van builds have a small number of miter cuts, not enough to justify buying. Borrow one for a single weekend session when you need it, or have a lumber yard make the cuts.
- Why can't I borrow a wire crimper instead of buying one?
- Electrical connections are safety-critical — a bad crimp causes heat, voltage drop, and fire risk in a structure you sleep in. Borrowing a crimper creates pressure to rush electrical work or work around availability. The tool costs $20–40 and is worth owning for the safety argument alone.
- How much do van conversion tools cost in total?
- Buying only what belongs on the buy list runs $195–350 for the core kit plus bits, blades, and fasteners (Estimate). Renting a circular saw for sheet goods cuts adds $25–40. Total build tool cost is typically $220–390 for a first-time builder (Estimate).
