Best Method For Testing Head Gasket Leak

Truck looses coolant only when towing after about 3 hrs to the point of needing more, when it sits theres never any coolant leaking on the ground
we have had 3 mechanics try and figure it out but none of them can and it does not have the solid upper rad hose after use

I used to own an ant farm but had to give it up. I couldn't find tractors small enough to fit it.
