We Love To Talk Vans!

Building out a van or RV can feel overwhelming—but you don’t have to do it alone. We have years of experience both in mobile living as well as mobile upfitting. Our Build Planning services give you expert guidance at every stage, from electrical and plumbing design to layout advice and equipment sourcing. We’ll help you avoid costly mistakes, choose the right components, and create a clear plan tailored to your lifestyle and budget. Whether you’re tackling a DIY build or preparing for a professional conversion, we’ll make sure you start with confidence and a solid roadmap.

Layout Design

A well-planned layout makes all the difference in how your van feels and functions. We’ll work with you to design a floor plan that balances comfort, storage, and usability—tailored to your lifestyle and travel goals. We’ll help you maximize every inch so your van feels like home.

Water System Design

A reliable water system is key to comfort on the road. We’ll help you plan a plumbing setup that fits your travel style—whether that means a simple sink system or a full hot-water and shower configuration. Our designs focus on usability, adjustability, and easy maintenance

Electrical System Sizing

Getting your electrical system right starts with understanding your power needs. We’ll help you calculate daily energy use and design a system that can handle it—whether that means a compact setup for weekend trips or a full off-grid solution for long-term travel.

Purchasing

We work with companies such as Owl Van, Aluminess, Campervan HQ, Freedomvango, Velit, Flarespace, and more. If you need parts or components we can order them straight to our shop.
