LOVED BY THOSE WHO SEEK THE MOST OUT OF LIFE
Don't take our word for it. Peruse these real-life stories from our customers.
My wife was hesitant about van life, but Rossmonster’s premium craftsmanship won her over. After researching 50+ companies, I chose them for their expertise, partnership approach, and honest, straightforward process. Luke Farny was incredible—always collaborative, never dismissive. Their efficient build and good-faith business practices made the experience seamless. Years later, they even helped me sell the van—an outstanding partner from start to finish.

HIGHLY RECOMMENDED
- J. W. Penland
We approached several big-name van builders, but most couldn’t deliver on our full vision—until we found Rossmönster. Their Scandinavian-inspired craftsmanship and client-focused approach stood out immediately. From our first call with Luke, it was clear they were excited to bring our ideas to life. Throughout the process, they handled our endless questions and any roadblocks like true pros. We couldn’t be happier with the result and can’t wait to start making memories in our dream rig!

THEY MADE OUR DREAM RIG
- Jomanda Peacock
Working with the Rossmonster crew on our Promaster was an incredible experience from start to finish. Their team was kind, patient, and communicative throughout the entire process, and their post-purchase support has been outstanding. Luke and Ross went above and beyond to bring our dream van to life, down to every detail. Even years later, they’re quick to help troubleshoot and keep our van running smoothly. We couldn’t have chosen a better team—truly grateful for their expertise and care.

CREW ARE THE BEST
- Sean Madden
With 12+ years of RV camping, renting, and demoing, I can confidently say this was the BEST vehicle I’ve ever driven and camped in. My sister and I gave over 36 tours of the Baja+—even two sheriffs stopped us to check it out! The drop-off was just as memorable. Thor personally toured me through their impressive HQ, and the entire Rossmonster team was incredibly kind and welcoming. Their craftsmanship and attention to detail are unmatched. If you’re after the ultimate road-tripping experience, Rossmonster is it. I’ll definitely be booking again!

BEST VEHICLE EVER DRIVEN
- Christian De La Torre
We chose Rossmonster for their craftsmanship, experience, and reputation—and couldn’t be happier with our van. Beyond the build, their post-purchase support has been outstanding. Whether it’s quick questions or a major warranty issue, their team responds promptly and personally. They even arranged towing and repairs for us in California, handling everything seamlessly. Huge thanks to the Rossmonster crew for their incredible service and care!

BEST AFTER SALES SERVICES
- C. Kim Jester
After researching 20+ van conversion companies, I’m so glad I chose Rossmonster Vans. Working long-distance from Missouri was seamless—Luke and Sam made the process easy, professional, and clear. Luke patiently guided me through every option to ensure the van fit my needs perfectly. The craftsmanship and finishes exceeded my expectations. I’d highly recommend Rossmonster to anyone looking for a custom van build!

TOP-NOTCH CRAFTMANSHIP
- Tracy Ruhland
After checking out several van builders, Rossmonster’s bright, wood-filled interiors instantly caught our eye. We worked with Luke on a custom Ford Transit build and are so glad we did. He helped us fit a long bed, spacious garage, and full kitchen into a medium-length van without compromise. Communication was top-notch—photos, updates, and quick answers throughout. The finished van is a beauty, and the Rossmonster crew is simply awesome!

EVERYTHING FITS PERFECTLY
- Ellen Gerl
Working with the Rossmonster team was an absolute pleasure. Luke and Andrew were professional, responsive, and delivered our dream van—even amidst the challenges of the pandemic. Their process was well-structured, and they always offered thoughtful solutions tailored to our needs. After two months of use, the build quality is top-notch, and their after-sales support has been outstanding. Huge thanks to the Rossmonster crew—couldn’t recommend them more!

GREAT ATTENTION TO DETAILS

PRICING
When building a custom adventure van, costs vary based on your chosen floor plan, finishes, power systems, and climate control. We work within your budget, offering options at different price levels and ensuring transparency throughout the process. Custom builds typically range from $60-150k (excluding the van). Financing options are available—contact us via our request a quote form for more details!
We know that when you finally decide to pull the trigger and embark on a custom build, time is of the essence, and excitement is running high. As such, we try our best to keep lead times between 6-9 months and can occasionally work with you to expedite projects whenever possible. Once your build slot rolls around and your vehicle is in our shop, custom van builds typically take three weeks.
