Yellow gas line tape
I'm using a similar setup on a Coleman Roadtrip grill.
If you're using Teflon tape on the adapter fittings, get the Oatey yellow (color) thread seal tape. It's thicker than the more common white Teflon tape and designed for LPS / natural gas/ butane which operate at higher pressures than water pressure.
Under normal circumstances, your propane tank regulator would reduce the operating pressure to a safe enough level to use the white Teflon tape however, for a few bucks more you can have some piece of mind by using the yellow thread seal tape.
Congratulations on the new AS.
