Mystery coolant leak

04 ram 3500 hundred 24 valve. Coolant around the passenger side oil pan. Radiator is full, recovery about 1/4 full. Checked the clamps on the turbo and they're dry. Water pump is dry, hoses are good

I think the oil cooler is on the passenger side behind the oil filter.

That may be leaking down the side of the block...

There's a rubber flex coupler connecting two hard lines located between the block and turbo. The 2006 models were notorious for leaks from that rubber flex coupler.

That hose is a bugger to replace but is a very common leak source. Try just tightening the clamps. That may be enough to stop the leak if that is the issue.
