You'll probably need to replace that hose as well as the other while your at it.
If the outside temp is cold enough the lower hose may not get very warm driving around.
Since it sounds like you replaced your coolant you may have trapped some air in the system as well.
Run the engine with the truck parked (preferably in a garage with the front of the truck higher than the rear if possible) letting it warm up. Vary the RPM between idle to 2000 from time to time watching the temp gauge (it may also overflow the recovery bottle and the temp my go up higher then normal until the thermostat opens, but keep it going until you feel the lower hose starting to get good and warm) (If the temp gauge starts to go full peg shut it down). Let it idle for a few more min. then shut it down. Make sure the recovery bottle is full. Let it sit until its cold. Check the recovery bottle and add if necessary. If its empty, take the Rad cap off and top off the system.
Add...make sure you have your heater temp set to full hot and in vent position while doing the above.
