The work continues slowly, but continues. I’ve pretty much completed the internal wiring. I have two 6 volt golf cart batteries, which go to a new breaker panel:
That’s a marine breaker panel, fed through the 100 amp breaker on the lower right. That also allows serves as a master switch. There are two different kinds of lights. All led’s of course, and modern. The sconces use standard bulb of about 2.4 watts if I recall correctly, and the reading lights are supposed to be 2 watts. I haven’t actually measured them. The sconces let me set a background level wherever we are, and then use one of the reading lights so we can see what we’re doing.
The living room has three sconces and three reading lights.
I went kind of overboard in the kitchen. There we have eight reading lights. I hate cooking or cutting food and not being able to see what I’m doing. Also some of those lights can be pointed to illuminate the cabinets.
One sconce and two reading lights in the bathroom
And two sconces and three reading lights in the bedroom.
Note that we have a number of charging stations. Each is like this:
It has a “cigarette lighter” output, and two usb ports: 1 amp and 2.1 amp. There are two of these in the bedroom, two in the living room on the right wall, and one on each end of the kitchen. The two in the living room are on a separate 20 amp circuit, so if we want to use something with high current requirements we would use those.
The rest are intended to charge cell phones and tablets.
Next comes plumbing. The water system is mostly installed. From the wall water inlet we have 1/2″ pipe for pressurized water, 1 1/4″ inch tubing for water from a container, and 1/2 inch tubing for a vent. Those are all plumbed to a 41 gallon fresh water tank under the sink.
From there it’s half inch pex pipe to the pressure pump. The cold lines from there are all pex, and the hot is all 3/8 copper tubing.
There’s a faucet and a shower. Shower lines are rather exposed. I need to make that look a bit nicer but I’m not sure how at the moment.
Next comes the propane supply. I did all the lines under the trailer with 1/2 rigid soldered copper. I know that the official recommendations are to use all black iron pipe. That’s because of the constant stream of gravel and other debris when it’s being pulled. But in this case the tubing will all be protected- none will be exposed. Copper is lighter and will last longer.
I haven’t bolted the propane tank holder down, but here’s what the front looks like.
I got one of the auto-switch pressure regulators. If one tank runs out and the other is full, it will switch over automagically. The lines come up into the cabinet under the sink on the left, and from there it tees to the water heater and the stove.
And on the left it comes up inside the cabinet in front of the refrigerator, and tees to the heater and the refrigerator.
I still need to wire the heater and water heater, but once they are wired and I connect the propane in front, we should have hot water and heat.
