A very small leak can cause that sweet smell of antifreeze in the cab. I've seen headgaskets, hoses, gaskets and heater cores all do it. Sometimes the leak is so small it won't even drip, but evaporate and leave a nasty green stain. This evaporation is what you are smelling. Pressure testing will help find leak. Do it with a cold engine and evaporation will be less of an issue. Sometimes the little leaks will even take a UV dye to help pinpoint.
you may have such a small leak in the heater core that your carpet may not be wet but still smell like antifreez. I'd check the heater core if no lines are showing signs of leaking. You can put some florecent dye in the coolant, run the truck then shine a black light on it to look for any leaks under the hood.
If heater core is leaking in truck, then it would drip on passenger floor board. Many times you will smell them with just a little leak. Also, most times when heater core goes bad, you will start fogging up windshield.
