Installing DC Voltmeter
I want to install a DC Voltmeter in my TT but not in the vicinity of the power panel / converter. The closest point to monitor trailer DC voltage levels is the 12 vdc block in the bottom / back of t...

The real answer is that accuracy or remote location vs at battery is IT DEPENDS ON LOAD.
If the wires from battery to gauge are not carrying other loads or only light loads, the reading will be accurate.
As load(s) on that wire go up, there will be a bigger and bigger delta between battery reading and the lower reading you get at the gauge.
So, if you can find a circuit that doesn't carry a load when you want to check voltage, it will be fine. The other extreme would be to tap into, say the furnace. With the furnace running, you would see a LARGE difference between voltage at battery and at the meter.
