Absolute precision in engine istruments is substantially less of a concern than change. When you mark the gauge, you're not nearly as interested in the absolute - though you can measure it for peace of mind - as you are in change. i.e. if the needle is off the dot, >why< is it off the dot. I've a nice set of digital gauges I'll likely put in the Ratrod if I ever make an instrument panel. They give absolute readings very well, but they're basically useless to see change unless you scan them long enough to digest the number and ask is it bigger, littler, or the same. That borders on the useless for the coach. Take Bob's approach. And as many of us do, ad the DigiPanel. It will get your attention if you're freeway fixated and something changes.

And if you want to see what the electrics are doing, put an ammeter - or two - in the coach. So it says 13.9 volts at highway speed. Cool. Is that 13.9 the float voltage of a charged chassis battery drawing maybe 4 -5 Amps at float, or a battery with a dead cell drawing 40 Amps? You'll find out when next you try to start the coach. Better to know ahead of time.
