As of 2024, we are no longer manufacturing the Nimbl Evolution.

However,

  • We’re proud of the work our team has done with the Evolution, and it’s a great example of the range of stuff we can build, install, and upgrade. This camper is a huge part of our background, so this page is here to show where we came from and what we’re capable of as a shop.

  • We’re continuing to provide service and upgrades for existing Evolution (and XP) campers, new and used.

  • If you like what you see, we do service and install work on existing overland vehicles!

  • We’ve made a lot of changes and improvements since we started. If you’re a current Evolution or XP Camper owner, you might be interested in some of the newer features or components. Don’t hesitate to get in touch!
