Perhaps ammeters could provide useful information, but who knows? So far I have not heard of one actually being used in a tiny trailer. Still, I am intrigued by the idea.

Plus you can gauge time to failure with voltmeter.... Time to failure being the "curve" when battery voltage is going to drop below levels that which 12 volt appliances cease to function effectively...
Ironically most cars now actually have abandon ammeters and now have voltmeters...

If that is the goal, why not just get it all hooked up, turn everything on and use a clamp-on meter to check for the loaded amperage.
