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...

What you suggest would generally work fine and be simple enough. You would be measuring the voltage at your control center, which may not be exactly the voltage at the battery...
To OP, I installed a volt meter I bought off Amazon, in the very rear of my 28 1/2' TT, 30 feet from my two batteries. I tapped a small always hot wire inside the hood of the stove and mounted the volt meter in the kitchen. I then tested the voltage at the batteries with a handheld volt meter, and I got the exact same reading, to two decimal points, as my meter in the rear of the coach was displaying! Accurate to the hundreth is close enough for me!
So personally, I would not worry at all about where you pick up 12V in your RV for the meter. My volt meter is on 24/7, not switched, but it's an LED, so I don't worry about the very minor parasitic draw.
