I'm adding a new gate in my vinyl fence; a full width (6') gate.
I'm concerned about support. The fence posts are decently moored, but there is still some wiggle.
Would it be better to dig out and add additional concrete around the outside of the posts and keep the posts hollow?
Or would it be better to add a 4"x 4" wood post insert and moor it with some interior concrete to moor it?
Or is there another approach?
