2020 tacoma vibration and right pull

Hello new here! I have 2 things to discuss. I have a 2020 tacoma 4x4 sr5 trim. Stock black wheels, stock tires. Stock everything. Had 2 alignments done by dealer I bought it from.had the truck 2 months.

This is not all the time but when I drive 70 to 75 occasionally I get a steering wheel vibration. The truck drives straight.

Ok secondly when I am on a road that is crowned like right side of thebroad slopes right, it really wants to go that way to the right more so any fullsiz3 truck I ever had.

Does anybody have any input on these two subjects. Appreciate everyone

I have dunlop tires on the front. At20 I believe. I heard many people hate these. Anyways does anybody have any input on thus. First time with a tacoma and didn't know if anyone had experience with thus.
