A few Updates:
Got the battery box in and of course I overlooked a couple things and had to take the top off because of a crossmember on the body and my support had to be modified but that's why I have a grinder with a cutting wheel. I was concerned about integrity, but after it was bolted in I am no longer concerned. There's still a nice space between the battery box and the underfloor storage. Might be a good place for a water tank some day....
Got the sidewalls insulated and added a built up wood stringer along the base of the windows. This is where I can attach panels and the structure of the cabinets. I bolted aluminum angle to the pinch welds along the bottom edge and will use the very bottom for running wires and it will get covered with a trim. I am taking Wonderboy's advice here and leaving wireways. This is my first rodeo, and I am sure I will forget something. This is the 3M thinsulate. So there is a layer of 1/8" ensolite on the metal skin, then thinsulate, then reflextix. Where I could, I stuffed the inner cavity with the thinsulate.
Insulation finished
Got the bench and belts installed and the boys got their first van rides. Did a road trip to Mammoth and they got their first day on the hill with skis!!
I try to keep multiple sub projects moving. These are the first parts to my bumper. Steel frame with aluminum shell. There are Comp 4x4 Heavy duty spindles. They come with the DOM sleeves which are inserted into my 3x4 1/4" tubing. Basically you put the spindles into the dom sleeve, get everything set, then weld in the dom sleeves and that will hold the spindles. You do tack the spindles into the sleeves. More pics on this as it goes together. Piece by piece.
