Amazing team of folks! I recently became a customer but (Havn). I'd been in communication with them for about a year and have made multiple trips out from NC to see their products. Couldn't be more pleased! Big shout out specifically to Luke, Ross, Thor, Patrick, Sam, and Trenton who were all extremely helpful throughout the entire process.

My wife and I purchased a Baja trail back in. Well, it was in 2025, we've put in about 20000 off-road miles on it. And about 10000 highway, and we love it. We would never, ever go back to anything we had before. There have been 2 problems we've had with our Ross. Monster, our heater failed to work. And within a few days, they scheduled a repair, at no cost at a very competent R. V. Mechanic, and then we had another time where we blew out our inverter, and it was our fault, and we needed some new slide rails, and they fixed everything. The inverter did all the labor and everything for free. We've never been charged a penny for anything that they've had to work on on this truck. They are a 5 star outfit. They are literally the best I've bought from several companies. They are by far miles and miles ahead of other companies. There are rigs are big enough to get off-road. But small enough to actually go down the trails. You want to go down and still live in luxury. If you haven't bought one of these, put it on your bucket list and go rent one or try one out. I know you're gonna want one. We have so much fun in ours. You can do anything with a good rear locker and some good suspension. And they will not leave you hanging.If you ever break down and you know, you're gonna break down, because that's just the nature of doing off road in an r v.But dude, they will help you like on the spot!!

Incredible team making incredible adventure vehicles. I picked up our Rossmonster Skye 144 Sprinter two weeks ago. Two thousand miles later now in Asheville NC after many days and nights of enjoyment we are so impressed with the level of quality and attention to detail. Well done Rossmonster.

We couldn’t be happier with our Rossmönster Havn. The build quality is outstanding and every detail feels solid, engineered, and designed to last. It’s obvious that craftsmanship went into it, not just assembly. Just as impressive is the team behind it. The service throughout the process has been responsive, thoughtful and genuinely supportive. They made the experience smooth and enjoyable from start to finish. How awesome to find an adventure vehicle that lives up to the hype and a company that stands behind it. We cannot recommend this vehicle and this company enough. Let the adventures begin!

My wife and I chose Rossmonster to build our van because of their experience as a custom van builder, build quality and their reputation. We are super happy with our van and the experiences we are able to enjoy because of it. But 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 warranty 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.

The Rossmonster Baja is our 5th camping rig (previously a VW van, Travato, Revel, EarthCruiser) and this is by far our favorite build — both in regards to design and quality. We finally have something that perfectly blends utilitarian design, offroad ability, fantastic comfort, storage, functional layout, and true 4-season readiness. Edit: Certainly a concern some may have is buying a rig from a smaller builder and the after-sale support. After 10 months of ownership I can continue to say the build quality is far better than any of the big-name builders and when anything does come up they are on top of it. Whether it be a phone/email consultation or having work done at their shop — either way they go above and beyond every single time.

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!
