......We ordered up a tachometer, a voltage indicator, an oil pressure gauge, a water temperature gauge (we didn't trust the factory one), and a boost gauge for the turbocharger we plan to install one day. We went with the full-sweep electric gauges so we wouldn't have to run pressurized lines into the cab.This is a compact truck, and there's not much room on the dash, so we also opted for Roll Pod gauge mounts that will bolt directly onto the bars of out rollcage. The one problem we ran into is having such a small truck and using such a big tach. Auto Meter does make a 3.375-inch diameter tachometer in the ES line, but they do not have a Roll Pod for this size of gauge. Therefore, we stuck with the 5-inch tach.
