Before you start cutting and drilling, let's talk about tools. This is another area where it's easy to overspend dramatically, especially if you're starting from scratch. But here's the good news: you don't need a professional cabinet shop's worth of equipment to build a great van.
I'm going to break this down into two categories: tools you absolutely need (Critical), and tools that make life easier but aren't required (Nice to Have). Remember what we covered in the money-saving section - Harbor Freight and budget brands work just fine for a one-time van build.
These are the tools you cannot build a van without. If you don't have them, buy them, borrow them, or rent them. There's no way around it.

This is one area where I'm going to diverge from the "cheapest is fine" advice.
Electrical tools need to be good because bad crimps can cause fires.
DO NOT CHEAP OUT HERE
A bad crimp can cause high resistance, heat buildup, and potentially fire
Worth spending: $50-80
Worth spending: $80-150 (or rent from auto parts stores)
For heat shrink tubing on connections
$25-40
Essential for troubleshooting and testing
$20-30 (don't get the cheapest $8 one)
For metal work and rust removal - get 4.5" grinder
$40 (Harbor Freight Hercules)
For demolition, removing seats, cutting metal
$60-80 (Harbor Freight Bauer)
5-gallon shop vac
$50-80
25-50 ft, 12 gauge minimum

$800-1,000
If starting from nothing (includes quality electrical crimpers)
These tools will speed up your build, improve quality, and reduce frustration - but you can get by without them if budget is tight. You can also rent some of these for a day or two when you need them.
For long, straight, precise cuts in plywood
Perfect 90° and 45° cuts every time
Way faster than sanding by hand
Swiss army knife of power tools
Way faster than screws for paneling and trim
Makes perfect holes in metal
$400-1,200
Depending on what you add
Don't buy Nice to Have tools until you know you need them
Bauer and Hercules lines are excellent for one-time builds
This is safety critical - get quality tools
Get tools when you reach that stage of the build
Friends with table saws, makerspace memberships
$30 to rent for a day beats $300 to buy it
One note on cordless tools: if you're buying multiple cordless tools, pick ONE battery platform and stick with it. Don't mix Bauer, DeWalt, and Ryobi - batteries and chargers are expensive.
For most people building on a budget: Go all Bauer from Harbor Freight. Their 20V platform has everything you need, the tools work great, and you'll save $500+ compared to premium brands.
$800-1,000
(with quality electrical crimpers)
$1,200-1,500
(adding some nice to have tools)
$2,000+
(not necessary for most builds)
Your van doesn't care if your drill is Milwaukee or Bauer. It cares that the holes are in the right place, the screws are tight, and the electrical crimps are solid.
Focus on technique and care, not tool brand names.
The best tool is the one you have and know how to use safely.
And seriously - don't cheap out on those electrical crimpers. Everything else on this list, you can go budget. But proper electrical crimps are what keep your van from burning down. Spend the extra $30-50 for quality crimping tools and use them correctly.
