Miles Van Camper (v3)

Miles Van Camper is an a versatile, off-grid capable camper van with a modern design built on a 2018 RAM Promaster (2500, 159″ wheel base, high roof, gasoline). This is my third Promaster conversion. You can read about the first one here (v1) or the second one here (v2).  Miles v3 uses the same floor plan as the first two but with minor improvements and tweaks.

Miles Van Camper has everything you would want in an adventure van all in about 65 square feet! Only high-quality materials were used. Check out all the materials I used for the build here.

I developed the unique floor plan after years of research and experience with other many other van campers. The layout effectively creates two separate “living spaces” in a small van footprint. In addition to the primary living space and galley located directly behind the cab, there is a bed/loft area in the rear that features a standard full-size memory foam bed, two windows and a powerful Maxxfan vent fan directly overhead. One of my design goals is to have everything work without much effort. For instance, since the bed is “fixed” you don’t have to make the it every day or store the bedding during the days. It’s very nice to be able jump into a comfortable bed whenever you want while someone else occupies the front living space or galley. If you need to use the bathroom you don’t need to pull the toilet out of a drawer or deploy curtains. Just step in and use the toilet or shower.

This van was sold in January 2023

Comfort / Safety / Convenience

  • CR Laurence “t-vent” window installed on slider door.
  • Two Motion Windows with screened openings installed into each rear cargo door.
  • Coleman Mach 8 Cub 9200 BTU rooftop air conditioner. This is the lowest profile unit on the market, and only consumes approximately 11.5 amps making it easy to operate off a standard 15 amp outlet/service (no need for 30 amp service). This unit will run off the battery bank/inverter but not for long!
  • Webasto gasoline-powered heater that runs off van’s fuel tank.
  • 10-speed Maxxfan vent fan can pull air into the living space or exhaust air out and features an rain hood so you can operate the fan in any weather, remote control and adjustable thermostatic control.
  • Combination propane gas and carbon monoxide detector.
  • Fixed full size memory foam bed in loft area
  • Isotemp SPA 20L marine-style, 5.3 gallon water heater that heats water while you drive with the engine’s coolant. It’s very well insulated and keeps the water at temperature for a long time. When you’re not driving, it has a 750 watt electric heating element that runs off the inverter and is controlled by a switch in the galley. The water is heated to up to 190 degrees in the tank and then mixed with cold water to a specified temperature when leaving the tank. This extends the 5.3 gallon capacity significantly and speeds up recovery time.
