As such I intend to mount a number of gauges in the cab to keep an eye on critical engine/trans readouts. What with the pitiful lack of modification available (it is a diesel after all) I fancy just making the cab like KIT or something

Long story short I finally found these.

The AUBER range of meters.
They couple to pretty much any type of sensor, have built in alarms and buzzers, can relay start an aux fan or some other safety device..
They also do a dual readout unit.
Dual readout
It fits inside the area of one 52mm gauge and has more than twice the usability what with the user set warning etc.
Price is great and reviews from the internetz seem pretty damn positive.
Being square you can also fit them really easy into din slots. I am looking at having three of the duel's, all fitting inside the space on one DIN


JJ maybe you would like to save postage and come in with my purchase? Wont be for a few weeks yet but its on the cards and pretty definate. I think my mate shane is going to have one or two for his truck as well so maybe get a 5unit+ discount or something. I'm just confirming they service the uk but they have paypalpayment and it all seems good on the shipping details so I imagine it'll all be fine. I just like to touch base with someone at the other end when doing international purchases.
If anyone has a different product that does the same thing I would very much like to know about it for research purposes. Otherwise this looks pretty useful.
Great for the trackludes out there as well.
What do you think?
