+1 common for the rad etc. to be plugged with oily crud. You can't clean it in the truck properly. Pull them out and degrease/clean and extend the puke bottle so it doesn't happen again. Even if it looks clean, pull it so you can look through it to make sure.

do you hear the fan kick in around 190- 200 degrees? at wide open throttle you can defiantly tell its working. Under normal load they dont usually kick in. Check the weep hole on the bottom of the water pump also, any drip and change it, cheap common part and 2 bolts. But it sounds like a fan hub issue, they are thermatic and if you fresh oil around the hub its also a sign.

Could be a few things. Dirty rad, dirty air filter, dirty intercooler or clutch fan not working properly...those are some easy things to check. Check the water pump as mentioned. Check the rad cap to see if it is holding pressure and then pressure test the coolant system. Sometimes the rad cap can come appart and part of it will cause a blockage in the coolant system. Air in the system can cause overheating. Lastly a blown headgasket can also casue overheating.
Hopefully it is one of the cheaper problems! Good luck with your truck!
