Better to have a little margin over the rated current that you plan to draw and fuse for. A heavy duty switch, within reason, will last longer.

The 150 amp one you are considering, if you do not have an inverter or plan to add one, is probably fine.

If you do want an inverter eventually, go for the 300 amp switch if you have room for it. My setup is using a 150 amp switch and 80 amp fuse for now. It’s all I have room for. If I do put in an inverter I have to upsize the wiring anyway, or add a separate circuit and stuff to power an inverter.

My 2018 19’ Bambi came with an inverter and I presume Airstream has used the appropriate wiring. Another user from another post had posted his Amp Hour Usage. It was an extensive list but one of the readings he had noted had the furnace blower running with refrigerator, inverter, television, cell phone charging, and living room lights full bright using 14.8A. That seems well below the 150A draw of the switch.

What does the inverter draw at full load? Or, for a rough guess what’s it watt rating?

Mine is a 1,000 watt inverter - which is 8.33 amps? To be honest, I have yet to use the inverter.

1,000 watts / 12.8v = 78.1 amps.

Minor decimal point error. Works out to 83.33 amps at 12 volts assuming 100% efficiency. Reality probably closer to 100-125 amps or more at full load assuming around 75% efficiency.

Based on that, the 150 amp switch could carry it, but I’d like some more margin. I’d go to the heavier duty switch. It would live longer and heat up less.

Racking my brains for my inverter usage (for those times I am boondocking) and all I can come up with usage of the TV and the computer. Neither of which would be used at the same time. Given those circumstances I would presume the 150 amp continuous switch would be plenty.

In other words, I would probably never run the inverter at full load.

Yup. If you are mostly under full load a 150 amp switch should be fine. An occasional full load will be just fine as well.
