Crown trim falling off

[Woodbine]

Good day in my 2017 Jayco bungalow one piece of the crown moulding trim near the ceiling is coming off what would be the best way to repair that looks like it was put in with some type of staple gun.
Thank you

Brad nails would probably be your best bet. I believe that's how they attach them from the factory.

Thanks for your help do you know what length I should use

It depends on the thickness of the crown. I would allow for 3/4 - 1" to penetrate the wall. So if the moulding is 3/4" thick, go with 1 1/2" brads. The usual rule is double the thickness of material.

I just replaced the inside door moulding in my rig and they were held in place with braid nails into the metal studs. I had to use counter sunk cabinet screws and drill a pilot hole for each one. I have a brad gun but was not sure if it would penetrate the aluminum.
