Murphy Bed Installation


Watch all my videos on YouTube!

A fold-up Murphy bed for a van is the ultimate space saver and a little effort can create a unique furniture piece.

12V System Setup

Watch all my videos on YouTube!

Now the solar wiring is in the interior of the van, I still have to attach it to the breaker box and solar charge controller.

The #8 AWG wire transitions to a #6 AWG wire at the breaker box, to minimize voltage drop, and continues to the bus bars. Meanwhile, I clean up the wiring with cable ties.

I add a 12 count fuse block and connect the wiring to the bus bars. Then the roof vent is connected to the fuse block with a 16 gauge wire. The roof vent allows me to fully test this 12V system.

This minimal setup is now ready for the batteries, which is shown in the next video.

Roof Vent – MaxxAir 6200K

The roof vent in an integral part of the ventilation, cooling and insulation plans. Living in an RV, one constantly faces the issue of cooling & heating and lowering humidity levels. With only few choices, I decided to install a MaxxAir vent; its ability to remain open, when rain is pouring down, made it a clear winner over its competitor the Fan-Tastic vent.

Episode 1

These are the initial steps of installing a MaxxAir 6200K roof vent in the rear roof section of a 2016 Ford Transit LWB MR cargo van. I go really slow and show every bit of the work that’s involved in getting an acceptable result.

Roof Vent Considerations

Converting a van often means that you’re working on multiple individual projects at the same time. Currently the Murphy bed with desk has my focus and when that work stagnates, I switch over to a secondary project: the roof vent.

That happens when you run out of materials or just when you only have a few hours to spend. But at the same time I might still be finishing up an already ‘completed’ project and/or preparing or ordering parts for upcoming modifications. Meanwhile, I may spend a few evening hours on the design and changes in design of the remaining project.

Today, it is all about ventilation. A small, enclosed space, like the interior of a converted cargo van, accumulates lots of moisture from breathing, cooking, etc. Opening doors and/or windows would be sufficient, as long as you’re on a one-day or brief multi-day trip.

Keeping Your RV Cool With A Hidden Floor Vent

Temperature, ventilation and condensation are some of the issues that complicates RV living. But keeping the vehicle cool and free from humidity and condensation may be addressed by installing a floor vent.

A floor vent in combination with a standard roof vent, should produce enough natural convection, that the airflow could sustain itself. By placing one vent at the bottom and the other at the opposite end in the roof of the vehicle, some of the conditions are created for a sustained convection airflow. A basic example is when warm air rises. For convection to happen, distance between the vents, a height difference and a temperature difference all play a role.

Are Floor Vents The Solution For A Hot Problem?

Floor ventilation for small RV’s could be an untapped resource, that has the potential to considerably reduce interior heat gain in off-grid locations and to significantly lower energy needs for 12V refrigerators.

Floor Vent Research For The Small RV

Boondocking is getting more popular as a cheap alternative for the full-time RV’er. For those of us that can handle the lack of air-conditioning, yet cannot stand noisy generators, many backcountry destinations are waiting to be discovered. Despite that Lithium battery technology may provide limited or full A/C-service in the future, currently temperature regulation in recreational vehicles is limited at best.
