Time for another update:
Let's start with solar. The 100W flexible panel was mounted and lines where run using Eternabond (in white) - this stuff is amazing. Word of advice - plan carefully as once it sets, you're not getting it off of there. The two solar cables run under the Eternabond back to the side rear pass through and into my MPPT solar controller.
I also added a remote display / controller that runs inside the sleeping cabin so I could monitor the system without going outside.
With the solar done, I finished off the rest of the power systems. Behind the wooden box there are 2 6 volt VMAX, 255 amp hour AGM solar tank batteries wired at 12v. They are supplying direct power to a Xantrex ProWatt 2000 watt continuous (3000 spike) inverter with a remote switch. The inverter is powering a heavy duty power strip that runs my TV, coffee maker, and mobile office equipment like laptops and phones (charging them). The shore power comes in through a NCCO pass through plug and immediately Ys off to a VMAX 20 amp charger that is permanently wired to the batteries and the other goes to a direct pass through to bypass the inverter if on shore power. All of this is fused and runs off of a master kill switch should I want to store the trailer for a long period of time. The system is strong enough to run my Climate Right 5000 Heat / AC unit off of the battery and the 20 amp charger will replace the used power faster than I'm pulling it. I would like to stress that I do not recommend this setup for normal deep cycle batteries as they are not meant to be used as pass throughs. This arrangement would rapidly decrease their life span. The solar batteries are the same as you'd use for your house if it were running off-grid and are designed for this.
It's done now, but there's some clean up to do in this pic with wire hiding and covering so please ignore the mess... Also added some light strips around the center shelf behind the shelf lip so you can't see them and they are hidden on all sides when looking at the back of the trailer. .
One of the switches on that panel runs to the water pump which I have installed to the right with quieting hoses and accumulator. The pressurized line then runs to a quick disconnect spray port pass through.
This weekend's project is to mount the on demand water heater and shower in the pelican case that is mounted on the side via quick disconnects.
Moving inside, the 60/40 convertable mattress is in, along with privacy curtains, and the 24" Samsung Smart TV is mounted on a swing out arm and powered through the inverter.
I intend to sleep with my head toward the front, (facing the TV) so I wanted a softer light than the LED light ring around the fantastic fan put out. (The fan and light are great, it's just really bright.) So I added a dimable touch light, that is flexible for reading or just low light in the cabin. (Ignore the toilet box, it's next on my build list.) Also added the black cup holders on each side by the doors.
Should be able to wrap up everything this weekend provided I can source the water heater connection parts.
