The kit allows easy adaption of AdWag MOAB bed, MONK bunks and MULE bags, as well as future proofing your van for some exciting future products from Adventure Wagon and Adventure Fitouts.

With a passion for perfection when it comes to fit, finish and function, the quality of Adventure Wagon products is unsurpassed, even when compared to custom builds costing much more. 

The Modular Interior System includes:
· Hushmat sound deadening
· Premium 3M Thinsulate insulation (pre-cut)
· A-frame steel bracing structure
· Pre-measured electrical wiring harness
· Maxxair Deluxe vent
· L-track mounting system
· Premium panels in a variety of materials complete with 12V & USB outlets. 

Adventure Wagon have recently enhanced the  interior system to now include the following:

  • Sleep sideways now with support for Flarespace flares and wider rear window panels
  • Added additional upper horizontal track for mounting ceiling cabinets, bags and providing extra tie downs for boards, rods, skis.
  • Extended the vertical track to the floor for mounting lower storage, rear bench, kitchen consoles, ski racks.
  • Our bed systems can now be lowered to the wheel well allowing you to stack two MOAB beds, four MONK bunks or combinations.
  • Electrical system offers easy integration of solar panels, charge controllers and additional cabin batteries including Goal Zero Yeti and Inergy Apex.
  • We added additional A-Frame steel wall support adding strength and simplifying installation.
  • Overall this goes in faster and offers more configuration choices for your 2007-18 or 2019+ Sprinter.

Our engineered Modular Interior System is designed to be installed in a few weekends by a do-it-yourselfer, or in a few days by a professional shop. The leg work of upfitting your interior has been done by us. The integrated system of wiring, ventilation, insulation, interior panels, and wall-to-wall anchor points provides a solid foundation behind your custom set-up. While speed of install is a huge benefit, your van conversion will have a professional finish with no compromise to the fit or quality.

Innovative, configurable sleep and storage options allow you to set up your van as dictated by your next adventure. And then your next one, and your next one. It is meant to be built upon as life dictates. Get what you need now and let it evolve as you do. Buy, sell, trade or make components that enable you to do you. We call it “future proofing” your build. Raise the MOAB bed to store your bikes under and sleep above. Fold your MONK bunk down from the wall and store your motorcycle beside you. Remove the bed in seconds and pick up a couch or simply have room to get your kids into their ski boots! When you drive the wheels off this van, move your components into your new one.
