A premier designer and manufacturer of custom Mercedes Sprinter vans, specializing in luxury interiors and exteriors built for modern families, executives, and travelers who demand more from their vehicles. With a commitment to craftsmanship, safety, and innovation, we are redefining what a luxury conversion van can be.
A LEGACY OF INNOVATION
National Traveler is built on a legacy that dates back to 1975, when William Ulm Sr. founded the company as one of the original pioneers in the conversion van industry. What began as a specialized upfitting business quickly grew into one of the most recognized and successful custom van manufacturers in the United States, with multiple locations serving customers nationwide.
National Traveler became synonymous with quality, innovation, and luxury—setting the standard for custom conversion vans during a formative era of the automotive aftermarket industry.
Today, William Ulm Sr. returns to his roots with a renewed vision: to bring the same entrepreneurial spirit and craftsmanship into a new generation of luxury vehicles.
