I want to install a 12V digital volt meter
I wanted to install a digital LCD volt meter with LED backlight display that I bought off amazon. I'm familiar and comfortable with 12V electrical and I have decided to just tie into a 12V connection...

Momentary switch is what I would do as well. Then you have draw only when you want to check the voltage and minimize your parasitic draw.
Alternatively, a battery disconnect switch may not be a bad idea for when in storage or between trips.
I originally had a momentary switch on my voltmeter but I replaced it. I didn't like holding the switch on when I wanted to watch the meter.
The parasitic drain of the meter is very low. If you don't want to watch the meter, just turn it off.
