Given your location, 220F is pretty normal for daytime driving during the summer. 225F is not too high for the oil, assuming it is a modern SN rated conventional or synthetic oil.
For conventional oils, you do not want to it to see anything north of 275F, as its performance will quickly degrade after that. For synthetics, 300F is the point at which things will start going downhill in a hurry.
However, unless you are running the engine full-out for extended periods of time, its oil should not even approach 275F in temperature. So you can rest easy with the new truck.
Now, if you decide to hook up a trailer with another truck on it and then go try to maintain 65mph up one side of a mountain, you should definitely keep an eye on the oil temps.
