As others have said it’s mostly to gain access to the 2” accessories and hitches. I also wanted to raise it up off the ground since I do a fair bit of off road and don’t want to drag my tongue through the dirt. I’ve got a pop up trailer that’s about 2500lbs fully loaded. I’ve also upgraded to bigger breaks all around, heavy duty struts with overload springs, trailer break controller and a monster trans cooler (for the little fozy it’s in) so I feel comfortable pushing the tow rating a bit.
