$300 is about giong rate for three gauge set up. Installation isn't that bad a friend and I put a set up in the F250 in about 3-4 hours, he's really maticulous.
Bought a used triple pillar pod from a guy who runs a diesel performance shop shipped for $230. He went to the four pod and sent a new pyro probe and a few other new parts but haven't put them in anything yet. The pillar is painted tan and the interior of the F350 and Excursion are both tan...
Monitoring your systems is invaluble if you tow, push, or run hard.
My friend tapped into the driver side manifold and screwed the probe into the hole, this was the hardest part of the entire install.
