DIY FAQ

DIY Conversion Van Kits FAQ

What is a camper van conversion kit?

A camper van conversion kit is a collection of ready-to-install components—like kitchen galleys, overhead cabinets, and storage benches—that help transform your empty van into a fully functional camper. Whether you're working on a Mercedes Sprinter, Ford Transit, or another cargo van, these kits are designed to streamline the DIY build process.

Which vans are compatible with your DIY van conversion kits?

Our DIY camper van kits are designed primarily for Mercedes Sprinter and Ford Transit models, including both 144" and 170" wheelbases. Many of our van conversion accessories are also adaptable for similar-sized vehicles or custom builds. Always check measurements and compatibility before installation.

Why choose a DIY van build over a professional conversion?

A DIY camper van conversion offers flexibility, lower costs, and a deep sense of accomplishment. You get full creative control over layout, materials, and timeline. However, it does require time, tools, and a willingness to learn. For those wanting high-quality craftsmanship with less hassle, The Vansmith offers professional builds and van camper kits that blend both worlds

Can I mix DIY with professional help?

Absolutely. Many of our customers start with a DIY approach and incorporate Sprinter van conversion parts or Transit-compatible cabinets from The Vansmith to elevate their build. This hybrid method allows you to retain personal control while ensuring key elements are built with professional-grade materials.

What materials are used in The Vansmith's van conversion parts?

Our van conversion parts and accessories are made in Boulder, Colorado using CNC-cut Baltic Birch plywood, eco-friendly upholstery, and premium Blum hardware. The result is a durable, sustainable, and easy-to-clean solution for your DIY van conversion kit.

What’s included in a typical van camper conversion kit?

Depending on the configuration, a van camper conversion kit can include upper cabinets, lower storage benches, kitchen galleys with sinks or refrigerators, and specialized solutions like wheel well cabinets. All components are modular, so you can pick what suits your build best.

Do your kits work for a DIY Sprinter van conversion?

Yes! We offer a wide range of Sprinter van conversion kits, parts, and accessories. Whether you’re doing a full DIY Sprinter van conversion or simply upgrading storage and kitchen space, you’ll find smart, modular solutions that are ready to install.

What's included in a complete sprinter camper van conversion kit?

Complete kits typically include electrical systems (solar panels, batteries, inverter, wiring), interior components (bed platform, kitchen unit, storage), plumbing basics (fresh water tank, pump, sink), and installation hardware. Specific contents vary by kit; check individual product descriptions for detailed component lists.

How long does it take to install a DIY camper van conversion kit?

Installation time varies significantly based on kit complexity and builder experience. Weekend warriors might complete a basic kit in 2-3 weekends, while comprehensive conversions can take 2-3 months of weekend work. Full-time builders often finish in 3-6 weeks. Our installation guides provide realistic timeframes for each project phase.

Do I need special tools for van conversion kit installation?

Most kits require standard hand tools: drill, saw, screwdrivers, wrenches, and basic electrical tools. Some may need specialty items like a crimping tool for electrical connections or a jigsaw for cutting. Each kit includes a recommended tool list, and we offer tool rental recommendations for expensive specialty equipment.

Are conversion kits compatible with all van models?

Kits are designed for specific van models and year ranges. Our most popular options fit Sprinter (2007+), Ford Transit (2015+), and Ram ProMaster (2014+) platforms. Always verify compatibility before ordering; our product pages list specific fit information, and our team can confirm compatibility for unique situations.

What is (will be) included in a complete sprinter camper van conversion kit?

Each kit includes interior components, along with hardware and instructions. Electrical, plumbing, and other surplus items will need to be bought separately. Details vary by kit, so check the product description.

Do you offer Ford Transit camper conversion parts?

Yes, we carry Ford Transit camper van accessories, upper cabinets, and galleys tailored specifically for 148" wheelbase models. These conversion van parts are designed for ease of installation and long-term durability.

Are your products suitable for first-time van builders?

 Absolutely. Our camper van DIY kits are built with user-friendliness in mind. Each product ships with helpful instructions, and our team is always available to answer questions about fitment, function, and installation.

What tools or skills do I need to install a van conversion kit?

Most of our customers have basic hand tools and a DIY spirit. While some experience with carpentry or power tools helps, many of our kits are designed to be installed by first-timers. If you’re unsure, our van conversion supplies are backed by expert support to guide you through the process.

How do I know which van accessories I need for my build?

Start by mapping out your layout. Think about how you’ll cook, sleep, and store gear. Then browse our van accessories interior lineup, including kitchen galleys, refrigerator units, sink cabinets, and storage benches. You can also explore our DIY Gallery for real-world inspiration.

What makes The Vansmith’s kits different from other conversion van products?

We combine timeless design, sustainable materials, and handcrafted excellence. Unlike generic van conversion kits for sale, ours are made locally in Colorado with attention to detail, durability, and style. Every product is part of a system designed to elevate your build—from weekend warrior to full-time vanlifer.

Do you ship your DIY van conversion kits nationwide?

Yes. We ship conversion van kits and van camper parts across the U.S. Our products are securely packed to ensure they arrive ready to install, wherever your build is happening.

Can I see examples of completed DIY vans using your parts?

Definitely—head over to our DIY Gallery to see how other vanlifers are using van conversion accessories from The Vansmith in their builds.

What warranty coverage comes with conversion kits?

Component warranties vary by manufacturer but typically range from 1-5 years. Solar panels often carry 20+ year warranties, while electrical components usually have 2-3 year coverage. We provide warranty coordination and support; if something fails, we'll help you get it resolved quickly.

Can I install components gradually instead of all at once?

Absolutely! Many builders start with electrical systems, then add plumbing and interior components over time. Our modular approach allows staged installation, letting you spread costs and learn systems gradually. We can help you plan an installation sequence that works with your timeline and budget.

Do conversion kits affect my van's warranty or insurance?

Vehicle modifications can impact factory warranties and insurance coverage. Most insurers offer RV or conversion coverage, but requirements vary by state and carrier. We recommend discussing modifications with your insurance agent before starting. Our team can provide documentation to support insurance applications.

What's the difference between DIY kits and professional installation?

DIY kits include components and detailed instructions for self-installation, saving labor costs while providing learning opportunities. Professional installation offers expertise and speed but costs significantly more. Many customers choose a hybrid approach; DIY for simpler systems, professional help for complex electrical or gas work. We can recommend qualified installers nationwide.
