Promaster Conversion

In 2015 I purchased a new 2014 Ram Promaster. From the start I knew that I wanted to convert it into some sort of camper van. Over the years I built out the interior however in April of 2021 I decided that the interior needed a new design that opened it up to maximize the space. My Newfoundland is a fairly big dog. She needed more space to move around in the van.

I wanted an open design that with no walls or partitions. Also wanted to have a hallway from the back of the van all the way to the front. Taking advantage of the double doors, which is fairly rare for the Promaster, the new design had to have no obstructions between the two doors. With a clean sheet of paper various designs were drawn up. Over several weeks of drawing up one design after another I settled on the final version.

The new build would be completed in phases throughout the 2021 summer.

Phase 1

1. Purchase and install a Fiamma Roof Rack and Awning.
2. Modify custom solar panel frame to fit into the Fiamma roof rack.

Phase 2

1. Strip out all previous items from the van.
2. Wire for 12 volt and 120 volt outlets and accessories.
3. Build the interior per the design.
4. Paint front plastic white to match van.

Phase 3

1. Upgrade Renogy 1000 Watt inverter to a 2000 Watt.
2. Add a second 100 AH Gel Renogy Gel Battery.

Phase 4

Purchase and Install HVAC unit.

Home Generator

Home    Promaster    Trailer    Trailer Awning

I purchased this recently for emergencies when I loose power at the house. For camping I have 2 Powermate inverter generators with a parallel junction box. That will provide 3200 watts of power.

For home use I wanted a dual fuel with electric start. The Westinghouse brand is reportedly a very high quality and reliable generator. Since I rent I do not want to power the house. When power is lost at the house for several days I can power the Promaster and camping trailer with all the essentials: both refrigerators, microwave, toaster oven, heat or AC and most important a k-cup coffer maker.
