Is it raining? Does your truck have air conditioning? If it does, look for the 4" rubber hose hanging down on the passenger side of the firewall under the hood. If water is dripping from there, that is the moisture that condenses when you have the air conditioning running. (The AC runs in defrost mode too). If it's coolant, the heater core is leaking.
