Replaced lower hose. Replaced thermostat and radiator cap. Losing about 1 gallon every two weeks but do not see it on the ground. Engine seems to run normal. Thoughts?
have the same problem?

It must be leaking internally. Have you had a cooling pressure test done yet? That would be the first step, then see if the pressure drops. If the pressure doesn't drop, you may have a very slight leak based on temperature. You could perform an engine leakdown test and check for air bubbles in the radiator/coolant to see if the headgasket is leaking.
