First floor plan.
I've had a design like this in mind for a long time, but finally got it drawn up. Not everything is to scale. Like, I don't know the exact position of the door, or what the interior dimensions will be after insulating and stuff. But this will help with figuring out where the wiring has to go, and if I'll have room for everything I want in there.
Here is the front and back of the trailer. Front is kitchen, and I found while doing this that the microwave will not fit in the electrical closet, so I moved it to the kitchen. Which means I'll need the microwave outlet there too. May as well double as a convenience outlet. The microwave will only work through grid power anyway. Two of the six ceiling lights will actually be mounted under the upper cabinet thing that holds the microwave and water jug. I don't know yet the exact size or height of the windows.
In the back there are the cargo doors, a window, and a bed with storage underneath. I plan to have the storage accessible from both the inside and through the doors. The little convenience console thing will be at the head of the bed at an angle, and above will be a flat spot for glasses and phones and small things.
On the left is a fold-down table, and some overhead storage and a window, which I don't know the sizes of yet. The headboard console thing is way bigger here than it will actually be for real. Just keeping it recognizable. I plan to have a fresh air fan by the bed, and an exhaust in the kitchen. The roof will be entirely taken up by solar panels, so no room for a vent up there. And a CO detector is always a good idea.
On the right will be overhead storage at the foot of the bed, and the electrical cabinet. I got dimensions for the A/C and fridge online, and the battery/electrical area is based on what room is left. You see why the microwave won't fit, LOL. I may need to find a shorter refrigerator, and I'd like to maybe put the A/C a bit lower so I have more room in the back for venting. I figure I can't go wrong with a fire extinguisher and first aid kit. And a long time ago, I saw someone hang a waste basket on their camper door. I thought this was pretty cool. It's available inside and outside with the door open, and I won't have to worry about accidentally kicking it over.
That's it for now. Lots of changes to the wiring diagram, but I won't post that for now, since it will probably change yet again. Also, I may be buying the trailer sooner than I thought. Have to see how things work out first though.
