Low water preasure at kitchen Fauset

[Ricefarmer]

We have very little water pressure at our kitchen sink Fauset, on our 2020 Montana. Has been that way since day one. As soon as you turn it on it has ok pressure but within a second it drops way down? bathroom sing is fair as is the shower. Does it have a water saver? doesn't seem to have anything blocking it.
Any Recommendation's?
We're on park Water with plenty of pressure, have no control pressure valve installed.
