2015 F250 Coolant Leak

I noticed an orange puddle on the garage floor. After looking underneath I found what I thought to be the leak. It was the lower radiator hose that goes to the front of the motor. I removed the hose and replaced the o-ring. Job complete. About 1 week later I see another puddle on the floor. Unfortunately I was unable to crawl under this time to track down the leak. I take it to the shop and I find out the radiator is leaking on the driver side. I have that fixed. Leak's fixed! Not so fast. The truck is parked at work and there is a shimmer of wet underneath. More anti freeze. The truck goes back in the shop. The system was pressure tested and was found to be the first o-ring that I replaced. That was switched out and good to go...so I thought. There is still a leak and I'm not taking it back to a shop unless I have to.

What I have since noticed is that the main overflow tank on the back of the bay on the driver side is low. I topped it off with about 1/2 gallon this morning, didn't drive it since topping it and it is leaking onto the floor. Any thoughts on where to look to try and track this down?
