Well i start the bed, attatch the spare tire and add a battery to the trailer today.
Here is my idea for the bed. Fit a queen or double air bed, since i have both.
Enough space under for rubbermaids. Easily converted to a couch during daytime hours.
There will be less than 16 " between 2x4 supports. Should work. If i need more ill add them in. All of the 2x4's except the longer diagnol one should slide together under the plywood to make the couch.
As for the battery. My lights work when the trailer is plugged into the truck. So i am going to attatch the same 7 way plug to the battery so i just unplug the trailer from the truck and plug it into the battery. Voila. Simple.
I am also going to try to add a hole from inside to outside for passing electrical or propane lines through for my heaters. Something that will also be weather guarded when not in use. Simple like this :
