Truck over heats
This might be a long shot but make sure the radiator cap is on correctly. You should see a ling that will run parallel to the radiator if it is installed correctly. If not, you will overheat.
If the hoses are cool it's not circulating water. Check thermostat
Check the fluid level IN the radiator, not the reservoir. If low, fill it up.
If your hoses are cool there is no flow, replace the thermostat. If that doesn't fix it then the only other thing would be the water pump
If you drive a dodge that's normal
