totalizers are great but it's so nice to have fuel level gauges that actually work (compared to my cessna).
With the new 10-point calibration systems you can get pretty accurate readings.   ....comes in handy if you DON'T top off your tanks every time, which you won't if you have a load.     ....also gives you a clue if you have a leak or someone forgot to put a cap on or someone siphoned your fuel off in the middle of the night
