I have a transmission temperature gauge in my K2500. I also have a larger free-standing vacuum gauge mounted to the bottom edge of the dash that you can actually read while driving. It is color keyed with idle,economy,cruising,and power zones as well as numbers.

My '67 C1500 will have an tach/air gauge because it'll be a manual with air bags in the rear so I can haul with a 6" drop w/o a c-notch. I have a large dial vacuum gauge in a chrome pod from a 60-66 Pontiac.

I really like having a vacuum gauge to monitor fuel mileage,as well as tuning. It's amazing how with a slight lift of the foot you can maintain the same speed yet increase the air to fuel ratio for better mileage. Car makers should have been doing this for all these years they've pretended to care about fuel efficiency. It does the same thing as what these digital electronic economy monitors do in vehicles in recent years.

I like that cluster Steve showed. I always thought I'd add a clock,but these days stereos always have one or the cell phone is always handy. And,another gauge is more important. A large vacuum gauge would be great top center.
