Seller's Description

My wife and I bought this van brand new and as a shell in the Spring of 2020. We built it out to our liking during that Summer of 2020 and have been doing 3-6 month adventures in it since then. The van currently has about 29,000 miles (and counting!). We are based in Wisconsin, but are currently traveling around Colorado, Arizona, Utah, and Wyoming. We will return home to WI in May, but would be willing to work out a delivery for anyone interested that isn’t able to get to us. We are also open to accepting offers. Functionality/Layout: We built this van to serve us and our lifestyle. We made a space that allowed us to both work remotely from the van and be able to take video calls without being right on top of each other. There are two separate work spaces within the van for this reason. We have two dogs who traveled with us as well so we knew that a big bed was necessary as well as bench seats to double as dog beds. We created a storage space in the “garage” for our skis and also built a wardrobe to hold our ski gear among various other clothing items. Below our wardrobe is the slideout composting NaturesHead toilet; conveniently located between the two workspaces so that it doesn’t interfere with anyone's working day. There is a large cabinet running the length of the whole van which stores our clothes, pantry items, toiletries, and coffee supplies. We built our van with the intention of having enough solar so that we could both work remotely and have enough power to run our Air Fryer. We didn’t like the propane or gas powered cooking options available for van life so we opted to be able to cook with our Ninja Foodie (game changer). We also didn’t like the idea of using space for a shower since there are various options to shower while on the road and space in the van is a precious item. For this reason, we opted for the huge farmhouse sink because we could easily wash our hair inside the sink if needed. The van seats in the front both have the capability of swiveling, if desired; however, we rarely used this option because we had ample seating space in the back. We built a small storage console to fit between the two front seats. This stores all the good road snacks, prevents dog thieves from entering the front seats, and was an award winning coffee mug holder of all sizes each year. The van heater was thoughtfully placed under the bench seat behind the driver seat. We personally loved this set up because one of us enjoys a warmer working station and the other runs warm and prefers to have the ambient heat. We spent significant time insulating the van so we could ensure it would be comfortable in both warm and cold temperatures. There is storage under both bench seats for more clothes, personal items, or maybe dog treats. One bench seat is set up with a lagun mount and a bigger overall desk and the other bench seat has a custom desk space that slides into the wall when you want to use it. The van is completely off-grid. We’ve comfortably stayed a week (or as long as our food and water supply would allow) on BLM land with beautiful views. Materials: The cabinets are custom made from ¾” birch plywood with shaker-style doors with locking latches and gas struts Waterproof luxury vinyl plank was used in the main area. The ceiling is made from walnut stained pine wood slats A large sliding window was added behind the driver side door ¾” Extruded Polystyrene (XPS) floor insulation below ¾” MDO Plywood Subfloor Wall and ceiling were insulated with polyiso foil faced insulation ranging from ¾” to 2” thickness.

The LiBim charges the batteries while you drive. You can plug in the van through the shore charger and Victron Multiplus inverter charger, but we’ve only ever done that once in about a year of travel.
