I decided to change the vacuum pump to another that I located on Ebay to go to just one pump.
Much of the wiring has been completed and tested. I bought a set of large crimpers at a good price, (thanks Mike) to make up the battery cables, it was much easier than the other method I had been using, a crimper that you had to use a hammer to crimp the connection.
I ran all the vacuum lines on the truck to the reservoir and the heater controls as well as in the

control box.
A location for the charges has yet to be determined, they could be in the front, or with the batteries. Guards for the motor and electronics against water damage still need to be made, I have some sheet rubber, but may use some aluminum also.
Battery location and quantity has changed, they will be in the bed of the truck and be 12 volt rather than 6 for ease of service, weight, cost, and less range requirements; this can be changed at a later date if things change or go to lithium.
The gauges in the cab still need to be tackled as well as finishing the control box, running power cables under the truck, building the battery enclosure, plumbing the air shocks, and making the emergency disconnect setup. Although it sounds like a lot it won't take too much more to finish

to the point of finally ordering the batteries.
