I rounded my 4000 psi concrete for proper drainage, dipped posts in sealer, sealed around the base of the post with tar after two weeks and keep the posts sealed every few years.As a landscaper I deal with old pressure treated wood all the time. The failure point is always right at the ground where the post meets the ground (typically 10 years), the rest of the post will be totally fine. With 6x6 posts connected to concrete with brackets, it will last for a very long time.
