I can get the tare weight off the bottle and weigh the bottle to get the difference

I keep a handheld luggage scale for this purpose. It's easier to carry in the RV and is fairly accurate enough to judge the tanks.

This also works great, so you don't have to remove the tanks. However, you need to remember that there is a 20% expansion gap at the top of the tank to allow the propane to expand, even in a fully filled tank with 30 pounds of propane. It's a good idea, when you get a tank filled, to apply the hot water method, and see (mark with a sharpie) where a full tank actually does change temps....so you will know how to judge what is a half-filled, quarter-filled tank, etc, later on in life when you do the hot water method.
They also make a $60 ultrasonic tool that Doug needs, that will show the level.
