dissapearing antifreeze?..
06 5.4l f 250 no mods just a set of headers with factory exhaust and 40,000 miles on it.my troubles began with a burnt up plow motor during the snow storm .after i fixed it and was out and about i had parked for ten mins when i went to get in i noticed a "pool " of fluid running from underneath my truck. upon inspection i noticed a bad drip from the clamp on the bottom hose on the radiator. i drove home and when i looked at it it was dry as a bone no fluid leak.i refilled a gallon of antifreeze to bring it to full with radiator warm.rechecked next day was another gallon low.rechecked next day below low fill line but holding no drips and oil is clean not murky or cloudy. any ideas thoughts . i got ghost anti freeze

Worst case is that you have a leaking head gasket and the fluid is being burnt out the exhaust. But that is very unlikely, particularly since you have already seen it leaking. You can bet it is still leaking, but you just are not seeing it. The usual way to find that is to pressurize the cooling system and see if it holds pressure, and if not the leak may show up under pressure. Any shop will have the tool to pressurize the system. Likely places for leaks are any hose, the water pump shaft, the thermostat housing, and the cabin heater coil.
Since you've already seen that lower radiator hose leaking, that's a good bet and a common place for a leak. Old hoses often will not reseal because they get spongy, so I would get a new lower hose, and then double clamp it. I always double clamp radiator hoses.
