Based on all the info you've given. It doesn't sound like a coolant level problem, doesn't sound like a blower problem, doesn't sound like a heater valve problem. The only thing I can think of at this point is to flush out the heater core? Other than that maybe the temp door in the a/c/heater case is jammed or the control cable came off?

I tried finding a diagram of the HVAC box on your truck and I can't find one.

The heater hoses run along the firewall and go in behind the glove box.

Well I found the root of my problem. The previous owner who lived in Florida had bypassed the heater core. When I hooked it back up, I realized why. The Pipe going into the heater core had been deformed somehow, so coolant gushed out from the hose connection when the truck was running. I took off the hose and wedged a socked in there to get it back to a circular form and hooked it up again. worked like a charm. thanks for the help fellas.
