I never find any puddles under my truck. I fill the resevoir one day.... a couple days later it's empty. Can't find a leak.

I agree with Oracle. Check your hose clamps and connections (if you're investigating for yourself), that's where hoses will weaken first because of contact. While there may not be "puddles", the coolant could simply be evaporating (perhaps it's dripping onto hot metal somewhere) - so it wouldn't get as far as the ground!
Try this... when you park for the night (after driving until the engine is nice and hot), put a large piece of cardboard on the ground under the car. Any pinhole leaks will leave telltale stains behind.
If you can't find something obvious, you really should take it in for a mechanic to give it a look. You do NOT want to crack your block!
Good luck, let me know if you're successful in tracking it down! :)

Confirming that the resevoir is really empty and the coolant level is not just down to the "COLD" level?
If that's the case, and there is no evidence of leaks anywhere (water pump, around the head(s) etc), there's only one other place it can be going: out the exhaust system. And that's usually a leaking head gasket.
If it is a head gasket and it is caught and fixed immediately there's usually no damage. Ignore it and it may result in a major failure.

First things first. If you are positive there are no external leaks. Check exhaust when you first start after overnight sit. If there is even a whisper of white smoke you can be sure you have a leaking head gasket although if the leak is small it may not let coolant in until the engine is hot. Best test is run till hot, rad full , and cap removed, spark plugs removed. Pressureize cyls. one at a time with compressed air and watch for bubbles in coolant in open rad. Also pay particular attention to each spark plug as you remove them. That will often tell you which cyl. is involved

take it to the local radiator shop or maybe you have a mechanic buddy ---- bad water pump __ pin hole leak in a fluid hose __ bad seal at thermostat housing __ bad head gasket ((look at oil dip stick and see if the oil looks grey-bubbly)) __ leak in heater core __ small leak sprays onto engine block and motor heat dissipates the radiator fluid and appears as no puddle .. ALL the above are the most common and obvious of reasons to loose coolant _____

Year, make, model and engine would be a lot of help.
Knowing what engine you have would be the most help.
Why does everybody think headgaskets are always the problem?
If it is a GM V-6 most likely it is intake leaking.

That might be really, really bad! If there are no leaks you can see, did it ever occur to you that it has to be going someplace. Drain your oil pan, i bet that's where it all went. The oil will look like snot. Nasty green or yellowish. good luck, figure this one out soon.

You might have a leaking head gasket. It is letting the coolant into a cylinder and is burned out the exhaust. You might need new head gaskets.

You have a pinhole leak in the system

You drive it till it's empty? Forget it.
