Heres the real 'FlameKing' tray...

Next step was getting rid of the 4 pin and going 7 pin.. so I ordered the 7 pin junction box with wire from Amzn for $32..
The 4 pin was good but I want a battery box and I wanted the interior light to be on the 'black' wire from the truck and not the 'tail light' wire.. now I won't need to leave my truck attached and parking lights on..
I simply took an 18" 4 pin jumper and cut it in half.. so my factory 4 pin stays in tact and plugs into the 7 pin box..

I also opted to buy the $9 breakaway switch and mount it up in case I opt to add electric brakes later..
I wired that into the junction box, but dead ended the other end and zip tied it to the frame for later use..
I also got the $6 "Group 24" battery box from Amzn.. and put that on as well.. I need to make the difference in height up.. I read I person used a 2" PVC pipe. so on top of the battery box I will use 2" PVC (or elec conduit in 2") at like 5" and use large panel washers inside the battery box for mounting the 'tube' to the the top.. then when I screw down the propane spinner it will have a stable and even bite..

I opted to use 10AWG for the 12v going into the trailer.. only intend on 2 cargo lights and the 12v (7 amp) Shurflo to be on it..

I am waiting on the BlueSea 6 circuit panel from Amzn..
I did find a large piece of cardboard at work and traced the 'v-nose' and started figuring out the interior..

Dometic 310 toilet, 15" bar sink, 1.X cu ft fridge, 24x32 tub/shower, dual stove, 10 gal fresh tank..
Opting for a Full Size bed and that will be fine for me..
Will be doing 1" R-6 Thermasheath RMax or Dow Tuff-R 6.5 insulation in the walls and ceiling.. they run $20/sheet at locl HDepot..
Stay tuned..
