Missy – My Home

Missy is my home and on-going bus conversion, sorta tiny home project.

She is a 1998 MCI 102-EL3 ‘Renaissance.’ She started life as a tour bus.  I had a great deal of work to do to make her livable. She is now quite comfortable but FAR from finished!  We spend the majority of our time boondocking in the most spectacular places in the North American west.  The solar system provides for all of the electrical power – I don’t even own a generator.

First, why “Missy”??  Well…  I think that is how one pronounces “MCI”, is it not??  🙂

This is basically how she looked when we met…

… and how she looks currently. Well, sorta… changes/improvements are constantly occurring.

I have a very long way to go and lots of work to do…  Friends ask when she will be finished.  The answer is: “I have no idea.”

    Great blog, not particularly having to do with this post, but how do you manage fresh water and wastewater? You talk about having hot showers, so I am sure you are consuming fresh water and generating wastewater, so how are you handling it?

      Thank you Tom! Water management is definitely a concern – as is power. When I designed Missy, one of the important factors was that I wanted to be able to boondock for long periods of time. To me this means not having to move the coach NOR haul any liquids manually. So, I installed rather large tanks – 150 gallons of fresh water and 105 gallon combined grey/black tank (details here. I wanted that 105 gallon tank to be much larger but ran into some issues so had to settle. Turns out that it is sufficient.

      Hot water is supplied by a marine style hot water heater that operates from 120VAC and also has a heat exchanger that will heat the water from hot coolant (from the engine or diesel fired heater). I have not yet connected the heat exchanger but it is still on the to do list. To date, running the heater from 120VAC has worked adequately. When connected to shore power this is easy, of course. Otherwise, I limit its use to when I have sufficient sun to run it from solar/battery via the Inverter.

      I’ve stayed in one place as long as six weeks before needing to dump the holding tank and fill the fresh water tank. That has proven to be adequate. Longer would be neat but for my style of use would be excessive. After all, toting around 150 gallons of fresh water is nearly 1,200 lbs of weight! 🙂

Searching is half the fun: life is much more manageable when thought of as a scavenger hunt as opposed to a surprise party.
