I wouldn't give $.10 for vinyl fencing. It looks nice, but if you have any winds at all, it will take it right out.
My son has a cedar board fence with 6'x8' panels. A couple of years ago 2 posts broke off at their concrete base, from wind load, after about 20 years.. I think the post were cedar also. Plus the original owner hung the 6'x40" gate on a 4x4, so it broke also. Replaced with PT. Gate post is now a 4x6.
Early spring this spring, 2 more posts broke off. Directly opposite the first ones. Those had to be over 25 years old. I guess we know which way the prevailing wind blows !
Yes, removing busted off wood fence posts set in concrete and left in SE MI clay for 25+ years, requires digging, ingenuity, 2x10s, leverage, water and a floor jack. Very little cussing and no back trauma.
The fence panels are still in pretty fair shape, but could use to be stained
(low on my son's priority list).
