12v? 24v? 36...48v????
I'm very near to picking up a new travel trailer that I intend to pack with solar and LiFePO4 batteries. It's a 30A 120VAC RV. I understand the electrical wiring advantages of the higher DC voltage ...

Or from another angle, a higher DC inverter won't be as negatively impacted by the voltage sag when you really draw down hard to meet a big AC load like microwave or even go for the air conditioner.
In my opinion, 12v is not the best idea IF you regularly power large appliances with an inverter. For most RVers, I don't think this is a big issue, and 12v is just fine.
