My dash does not yet have a scanguage - but I plan on adding one soon set to transmission temperature so that I don't ever again blow the transmission like I did this past summer to the original ... with only 51K miles on it!
My cab currently has this extra stuff:
- One into two 12V receptacle expander.
- Four-place digital voltmeter to monitor engine alternator output.
- Four-place digital voltmeter to monitor voltage on the coach's 12V system ... and hence indirectly monitor the voltage on the coach batteries' terminals.
- Three-place digital ammeter to monitor current flow into and out-of the coach batteries.
- Two Cobra walkie talkies ... each with a built-in electronic compass and weather radio.
- Garmin navigator ... that also shows direction of travel, time of day, altitude, and miles to destination.
- Cab air temperature gauge.
- Driveway gate opener.
