Have your battery checked first.

You don't give any supporting info to work with!
Depends if it is a cranking issue, a engine firing issue, an idle problem etc.
Share some insight.

If this is the only difference, there is no obvious problem.
Colder temps normally raise the rpm on cold start and act like you discribe.
Don't discount lubrication drag at colder temps. It's a fact of life.
Best you can do is use the 5w20 blend or syn oil, be sure the battery capacity is good, charge system is working correctly, cable and terminals are clean and tight, fuel filter is in clean condition.
Cold start stratigy uses the IAT and ECT sensors to tell the PCM what fuel conditions will be, how much air to allow the IAC to pass and how long the high idle will go and how fast it will reduce.
Meanwhile the OX sensors have to heat up to at least 600 degrees before the PCM will use them to control fuel at idle and normal running.
Colder temps make the OX senors take more time to fully heat, just like anything else.
I don't think you have a problem, so far.
A sure way to make a difference is to keep the truck in a heated garage but then you have to deal with a cold start elsewhere.
