Roam Freely, Convert Boldly

Van Conversion Starts With Serg Supply

At Serg Supply, we've dedicated our business to bringing custom finishing options to the van conversion world, specifically for the DIY crowd. Converting a campervan can be daunting, and we understood that from the beginning. With a background in high-end home cabinetry, we brought what we learned to the van conversion world to create the most simple to install professional van cabinetry to the market to raise the bar on DIY van conversion projects and help professional builders meet their intended goals with their everchanging client needs. Serg Supply was built on the foundation of hand-made custom van cabinetry with attention to detail and a complete selection of products across all three major camper van platforms.  Our mission has always been to build quality van cabinetry for the DIY and professional builder to decrease build time and provide a genuinely unbeatable customer service experience for anyone using our van cabinetry in their van conversion. 

All our van cabinetry and wall and ceiling kits have been designed specifically for each camper van platform, Mercedes Sprinter, Ram Promaster, and Ford Transit. Laser measured and precision cut with our in-house CNC machine, we assemble and pack by hand to ensure our van conversion customers receive quality, unblemished kits and cabinetry to keep the build process going and make converting your first, second, or tenth campervan seamless from start to finish. 

Shop By Van


    Over the years we've converted hundreds of vans for customers who either don't have the right tools or don't have enough time. Our full service install team can take your van from shell to the mountains in under a month. We offer full service custom van conversions at both our Rocklin, Ca shop as well as Englewood, Fl. Take the guesswork out of converting your adventure van and drop it off to the pros.
