I've also been making a bunch of modifications over the past few weeks.
Completely replaced the main electrical system, including a new battery box, added a 600W DC supply to charge the battery bank when sunlight is not sufficient, more robust fridge plug, selector switches for solar 1, 2, DC supply, master disconnect. Deleted the inverter, for now, I may added it back later:
The solar charge controller is a Bogart unit, paired with the battery monitor that is in the cabin. I also put a LED light on the ceiling of the box, so I could sit and marvel at my handiwork.
Added some of that foam tile with outdoor carpeting laminated to it, as well as a small piece of doormat (not shown in picture):
Added voltage regulators to the Maxxfan and Propex furnace circuits so I can let the solar controller maximize the lifetime of the Trojan batteries by taking them up to the maximum voltage:
Some wiring cleanup remains to be done…
I see Mark liked my Lagun table install a whole lot.
I added a pair of directly wired and dedicated cig plugs to power laptops when using it as an office:
Last fall I added the 200W of solar panels to the roof:
Next on the work list is to add a couple of rocker switches and a 12v socket inside each of the kitchen slide out compartment doors to control the water pump, the side floodlights individually, and allow an outside awning lamp to be used. I'm going to use a relay to allow the interior switch to control both outside floodlights while they can be controlled individually from each side. The pump switch is going to be in the kitchen, because that seems way better than having it in the cabin.
