Trimetric Monitor, which is the best bang for the buck?

i have the 2030Rv. Everyone here talked me out of the 100a shunt. What if you later put in an inverter? Plus the 100a shunt gives you .x, where the bigger shunt only gives you x. accuracy. watching the x. numbers jump during solar charge is one thing, but I can only guess if your doing .X it would just keep changing that last digit.

Yeah, no solar, least not any time in the near future, namely because the less holes I have to make in 40 year old fiberglass, the happier I will be :).

I'm going to be flush mounting this into the side of the fridge cabinet, so that it's close to the battery bank, which will be contained in the two boxes that make up the dinette seats (which will help keep the camper weight ahead of the rear axle).

Smart gauge has some interesting design ideas, but having only voltage and state of charge does not work for me. I bought a Victron because I need to measure how much current (i.e. battery capacity) is consumed by the power users in my camper. I also want to use amperage data to help me optimize my solar system. Proper installation of the "shunt" was easy on my camper battery setup. In addition, I bought the bluetooth dongle for the Victron, which allows me to check battery data on my phone, without going to the display.

There are better (as in more accurate) monitors than the trimetric. Some of them are cheaper (Victron). The creme de la creme is the smartgauge which is now being distributed by Balmar in North America.

The smart gauge does not use a shunt.

"Because of its proprietary computer modeling and battery testing techniques, the Smartgauge™ remains accurate without need for re-synchronization"

The big selling point for me to use the TRIMETRIC model is it has a settable VOLTAGE ALARM feature. It is important for me to know when the batteries drop down to the 12.0VDC level (APPRX 50% Charge State) when camping off the power grid.
