Rattle on Start up

[Steve66]

First long trip in my 2021 1500 Limited. Drove from Ohio to Arkansas. About 800 miles. Bought the truck in October 21 and after 300 miles had to have a new engine.
Started the truck this evening and had a pretty loud lower end rattle on start up that lasted about 3 seconds. First time I have noticed. Truck has 7,200 miles.
Should I be concerned? Heading back to Ohio Monday.

Did you check the oil? Has it ever been changed?

Says under your name to the left you have a 6.7. That’s not right.

Thanks for pointing that out. It is a 1500 with the 5.7. Yes oil is good and 2200 miles since it was changed at the dealer.
