8,000 Miles

2020 Ram Promaster 3500 EXT
Builder: (


Mileage will ONLY be at 8,000 after a planned trip to the builder in AZ for yearly maintenance. We can also meet in AZ or I can drive this tank to you. The van will be available starting July 31. I will also gift you 99% of all my camping and other misc. gear.

I adore my van but was recently diagnosed with service-related disabilities that will make van life not as fun anymore.

159” Wheel Base, 250.5” outer length
Rear back-up camera
Cruise control
3” lift (The standard low clearance of Promasters is a problem if you want to go anywhere interesting without destroying your gray tank.)
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 upfit is 1150 lbs (same as an F-150)

1200W solar array
6000W Inverter (you can run the hot water, electric heating, and your hair dryer while baking a turkey)
Victron Charge Controller
3500W 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.)
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)

Vitrifrigo (top of the line Italian brand) 4.2 Cu. Ft DC Fridge (It is important to understand the advantage of a DC fridge: it doesn’t require you to have your inverter on all the time, which drains your batteries whether you’re using it or not!)
Thermostat-regulated electric heating (no dangerous fumes or emissions from burning fossil fuels in a confined space.)
Weboost cell-phone Booster
2 Burner electric cooktop
Maxxair Fan
Microwave (the pictures have the older one- there is now a smaller microwave)

Nature’s Head Composting toilet
46-gallon fresh water tank
100% heated and insulated water lines
15-gallon steel-encased gray water tank
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 (consider the logistics of using the restroom on a cold rainy day while your partner is still lying peacefully in bed… yeah, you want that 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 I got rid of all of them. Other builders will claim high R values in the walls, but that won’t do you much good if all your heat goes out the front and back of the vehicle! That’s like walking out in a blizzard in shorts and an unzipped jacket. It doesn’t really matter how good the jacket is if you don’t use it right.)

Beware! Most types of wood do not do well in wet conditions (van interiors get exposed to more water than you may realize). I therefore choose only the woods that are rated as “very durable” in terms of moisture resistance: white oak, walnut, and eastern red cedar.
Hand-made eastern red cedar closet and drawer bottoms (yes, it smells wonderful)
Hand-made walnut and white oak cabinetry and trim
Hand-made butcher block countertops and retractable table
Hand made white oak shower floor
Cabinet grade birch plywood walls
No formaldehyde-leaching particle board, no VOC-offgassing lacquer, no asthma-causing polyurethane fumes. The solid wood is finished with pure tung and orange oil. This is a slow and expensive way to go, but my team wants to apply toxic chemicals about as much as you want to live with them.

Additional features
Ceiling is 72.25” minimum
Custom stainless steel shower pan
Queen Bed platform is 75” long
Sliding bike/storage tray on 500lb slides
Two benches for seating around table
