Answer to how wires runs were hung
Several people have sent PM's asking how I hung long runs of relatively heavy wire (1 gauge). These runs were under my truck from the engine compartment to the electrical system in the bed of the truck. The photo below shows the wire running along the front of the bed (later covered by the water tank).
They system I used was borrowed from the marine industry and is called Weld Mount.

It is an amazing two part adhesive used to "weld" a stud to almost any surface. You then attach a wire (or hose) holder and clip it together with a 1/4-20 nut. The stud can be placed on a vertical surface, overhead and at any angle. The adhesive does not sag and sets in 30 minutes. Once set, it is permanent. The video on the weld mount site shows a single stud holding over 500 lbs of weight. I have beat on a stud that I placed in the wrong position with a BFH and could not remove it. The 1/4" stud bent, but did not come loose.
These are used in manufacturing larger power and sail boats to attach hoses, wire runs, equipment...almost anything to the inside of the hull of boats. I have used them extensively to avoid drilling holes and have hung long, large wire runs along the frame of my rig.
Check out the videos and website for this stuff. It is all they crack it up to be. A word of caution: Once attached, these things are permanent. Check position twice...adhere once.
