We just bought a 2021 Montana. We are on our first trip in it and I noticed that the fresh water tank is showing 1/3 full. I haven’t put anything in it but may have inadvertently. Where and how do I drain it ?

Those gauges are notorious for not being accurate.

The check valve in your water pump may have a leak and is slowly filling the tank.

Yep, had water squirting out my overflow once from a bad water pump.

I'll say that the others have probably nailed it with cr@ppy gauges and/or leaky check valve in the pump.

Interesting how Keystone totally cheaped out on these and simply put a cap on the end of the Pex instead of a factory-installed valve. My '04 Komfort used a 1.25" drain line with a blade valve and my current KZ has a standard Pex line with a 1/4 turn valve on the end, like the low point drains. Wish my KZ had the 1.25" drain line, that's for sure.

Or the dealer may have put water in the tank to do a systems test before you took delivery.
