What, Why & How
I have already more or less completed my caravan (travel trailer) rebuild as described in the earlier blogs. I want to be able to set up on a farm or large property somewhere and have basically all I need to survive. And thus I need a separate toilet shower and laundry space as I don't have this in my little caravan. I will put this next to my caravan and have a raised walk way between the two.
So I am building a little mobile unit that fits on top of my utility trailer. It can slide out and be moved via 4 detachable jockey wheels and adjusted for level. Once in position I can rest it on removable wooden foundations and remove the jockey wheels until I need to move it again.
The unit is being built mostly from recycled free materials so it is very cheap to build.
I used the remaining second hand tongue and groove boards that were also used on the caravan floor for my new units flooring.
And the walls and roof were made from an old refrigerator shed that was disassembled laying around on the property I am staying on and was given to me for free. So it has been re-purposed to live another day. It had a doorway and roof and a cut out area in the roof for the old refrigerator motor. I will use this hole for a skylight. The walls are made from 70mm thick refrigerator 'sandwich' panels (polystyrene foam covered in aluminium sheet).
A kind neighbour gave me a free new wooden toilet seat for my home made composting toilet. I also purchased a cheap urine separator unit to separate liquids from solids. Because the liquid and solid waste is separated there is very little smell.
The unit will be powered by a 12V cable from my caravan's PV solar system for LED lighting. And I will have a hole where I can put a 230V AC extension cable to power the laundry unit. I may buy a portable gas generator to power the washing machine if need be.
The shower will probably be powered by a cheap portable external gas heater unit used for camping.
If I wanted to set up semi permanently I could buy some more batteries and solar panels and buy a decent inverter for total power independence.
Anyway one day at a time.
