Do you love trailer parks? What about planned obsolescence? No? Neither do I! That's why I founded Vansion and designed our builds for intrepid travelers who never want to set foot in an "RV resort" or pay for a crowded campsite. As a second generation vanlifer, I understand the challenges of life on the road. Years ago, when my mom invested all her money in an RV, we thought we were buying a place to live, but it turned out the manufacturer didn't see it that way. After only a few months, all the cheap plastic and fiberglass parts started breaking, and when we called them up and said, "Hey! This thing is falling apart!", they replied, "That's because you're using it too much. It's a recreational vehicle. You're not supposed to be living in it." And that was that. Buyer beware. We also envisioned a life of adventure, close to nature in the great open spaces of the West, but reality set in again when we discovered that RVs only work in mild climates when they're plugged in. There is not a single line in the RV manufacturer's code book about insulation requirements. Additionally, RV park fees actually cost more than rent in the city! I know there is a large population living in vehicles, even though no vehicles are actually designed for that purpose, so now I build them. My vans are intended to be used as four-season homes for full-time nomads.

2021 Ram Promaster 3500 EXT

  • 159” Wheel Base, 250.5” outer length

  • Rear back-up camera

  • Bluetooth

  • Cruise control

  • 6-year warranty on coach


  • 1200W solar array

  • 3600W Alternator Charger (The solar array is sufficient for 4-5 days in extreme weather conditions, but the alternator is a game changer as a backup power supply for extended travel. This build requires no propane and no shore power.)

  • 6000W Inverter (you can run the hot water, electric heating, and your hair dryer while baking a turkey)

  • Victron Charge Controller

  • 800 Ah lithium ion battery bank (400 Ah relative to 24V) with state of charge display

  • Six-zone dimmable lighting

  • Four 120V AC outlets

  • 4 USB ports

  • This van is smart. It cuts nonessential loads (heating/stove/water heater) when the battery bank's state of charge drops below 15%, which protects the essential loads (refrigerator, bed outlets for cell phones and medical devices, lights, fans)



  • Nature's Head Composting toilet

  • 100% heated and insulated water lines 

  • 46-gallon fresh water tank

  • 15-gallon heated, insulated, and steel-encased gray water tank (It can take a rock hit and will not freeze in winter)

  • 4-gallon hot water heater (the water comes out as hot as you want it)

  • Fixed shower with 4 solid walls, shower fan, and a glass door

  • Reverse osmosis tap

  • Liquid soap dispenser


  • 200+lbs of 100% Pure Wool insulation throughout

  • 200 ft^2 of sound deadening mats (This van is quiet, really quiet.

  • Bulkhead and entry walls (These are not just decorative. You will understand the advantage of the bulkhead when you walk into the cab and feel a 40 degree temperature difference. Every piece of exposed metal is a thermal bridge, so we got rid of all of them. High R values in the walls won't do you much good if all your heat goes out the front of the vehicle!)

Upgraded Suspension

  • 3” lift (The standard low clearance of Promasters is a problem if you want to go anywhere interesting without destroying your gray tank.)

  • New 245/74/R16 Michelin Agilis Cross Climate tires (these along with the Promaster's extra wide wheel base give excellent control in all conditions)

  • New Sumo Springs 

  • Available payload after conversion is 1250 lbs 


  • Hand-made eastern red cedar panelling and drawer bottoms (yes, it smells wonderful)

  • Hand-made walnut cabinetry and trim

  • Hand-made white oak butcher block countertops and retractable table

  • Hand made 5/8” solid white oak floor (most conversions use cheap vinyl floors)

  • Hand made solid teak shower floor

  • Cabinet grade baltic birch plywood

  • No formaldehyde-leaching particle board, no VOC-offgassing lacquer, no asthma-causing polyurethanes fumes. The solid wood is finished with pure tung and orange oil. This is a slow and expensive way to go, but we wanted to apply toxic chemicals about as much as you want to live with them.

Additional features

  • 5-inch memory foam short queen mattress included (new in plastic)

  • Bed platform is 75” long

  • Ceiling is 72.25” minimum

  • Sliding bike/storage tray on 500lb slides

  • Two benches for seating around table

  • Two screened windows plus AC ventilation system. The bunk window invites a cross breeze over the bed platform while the inner entry window allows you to open the outer sliding door and enjoy fresh air without the bugs!

Building a van that doesn’t look like a house is easy. The trick is to build a house that doesn’t look like a van. These builds have inner stealth. You will forget you’re in a vehicle.
