You need to actually verify the tank is not draining completely.
"The tank gauge always reads 1/2 full and there always seems to be something in the tank when you look in it."
Tank gauges are notoriously wrong. And looking in the tank all you will see is "wetness". Stick something in the tank so you can actually measure how much water is in it. A small amount on the bottom is no big deal (1-inch ±). Several inches (2 or more) is cause to figure out what the problem is.
A bow in the bottom of the tank is quite normal and may hold an inch or two of water that will never drain. More than that may indicate something is blocking the outlet (or it may indicate you have a larger bow in the bottom - on an eleven year old unit that may be entirely possible).
