Loved by those that seek the most out of life.

Don't take our word for it. Read what real people are saying about our rigs and our team.

What real people are saying:

"As someone with over 12 years of experience demoing, renting, and RV camping, I can confidently say this was the BEST vehicle I’ve ever driven and camped out of. My sister and I gave over 36 tours of the Baja+ during our trip, and even two sheriffs pulled us over just to check it out—everyone was in awe, and rightfully so!

The cherry on top was the drop-off experience. Thor gave me a personal tour of their headquarters, even on a busy day. The entire team was so kind and welcoming, taking the time to show me their impressive operation and the craftsmanship that goes into building their vehicles.

For me, what really shows the value of a company are the people they employ and the support they provide post purchase. I have called the service support a couple times with questions on minor repairs and always had a timely and personal response. Recently however, I had a more major warrantee issue that required pictures of the problem to be sent.

Long story short...Rossmonster is located in Longmont, Colorado and I live in California. They researched repair facilities near where I live that could repair the issue. They arranged for towing from my house to the repair facility. We have our van back now and everything is as new. A huge shout-out to Rossmonster and their team. I am truly impressed with the friendly and competent interactions I have had with them.

We briefly toyed with buying a pre-built model they had available at the time, but instead began working with Luke on a custom build. So glad we did. With his design help, we fit a long bed, roomy garage and good-sized kitchen into a medium-length, high roof Ford Transit.

In the garage, we’ve tucked two mountain bikes and cycling gear, camp cook table, chairs and tons of other stuff.) Every question we asked got a quick answer. Particularly appreciated that Luke and Sam kept us in the loop during the build with photos and emails. The finished van is a beauty. And we think the Rossmonster crew is awesome!
