Air over hydraulic must have been considered air brakes. There is an air brake controller for trailers with air brakes, but I'n not sure how it's used or how it actually works. Obviously I've never used one.
My truck has 2 saddle tanks on it. Makes me think it can get thirsty. Scott, is that 6 to 7 mpg on the highway or an all around average?
It doesn't appear that any thought was given to the gauges when the conversion to 12v was done, but I'll look some more. There were 2 jars of tail lamps in the glovebox. It also has a knife type switch to cut off the battery from the starter. They moved the battery from it's original location because the mounting brace cracked and broke. I need to delve into the electrics some more.
