VAN BUILD WENDY

This was a van build based on a new 2021 Dodge Promaster 159" wheelbase. The design was based on the need for the van to be both a Class B RV and a work van with the ability to handle large cargos. The other objective was the van to be an ultimate "stealth van", able to park overnight and camp on any street in America.

We designed this van with the primary ability to switch between a work van and an RV in under an hour. This meant a bed design that opened up to provide front to back access of 144" of the entire length van to a with of 48". Almost all of the electronics and most of the appiances can be removed and easily replaced. Instead of expensive RV appliances Wendy has inexpensive appliances that be swapped out in minutes. If you need additional refrigeration during the holidays, then the two chest refrigeratuin units can be unplugged and moved inside a home. With it's 120V external outlet plug available, Wendy can be used as a back up generator for a home.

Another goal was to eliminate the complex internal electronics with a removable power supply. In place of over $4,000 of custom electronics we integrated a 3600 Watt Ecoflow generator system that could be added or removed quickly by plugging in just three power cords. The system could be charged from 480 Watts of solar panels on roof, van alternator, or 120V shore power. Because we did not need to build a complex electronics system involving multiple batteries, inverters, custom cable 12V harnesses, solar charges, and more we reduced the overall labor by over 100 hours, or $5,000.

To free up space on the roof for two solar panels and two skylights we designed our own two-fan ventilation system. Two low cost DC fans replaced two Maxxair units at a cost saving of over $900. In addition to the costs savings, the fans use ony 10 Watts (versus 80 Watts)of power permitting 24 hour operation. Because the roof vents are low profile we can install them beneath the rooftop solar panels permitting operation regardless of the weather. Since they operate with one as an intake fan and other as exhaust fan,the enitre volume of air in the van is replaced every five minutes.

Design philosphy:

As vehicles become more expensive, their use should be optimized for maximum return. With Wendy, the owner wanted the ability to take trips in the van, use it to move cargo, and also rent it when not in use. Because the owner can earn almost $200/day as a rental vehicle she wanted ability to make it a four season vehicle. The van has both a removable 120V AC unit and 12V diesel heater that can be interchanged for year round capabilities. The AC unit, however, requires shore power to be practical due to it's power consumption.
