Fence cap posts

Had a new fence installed last year. Probably 250 linear feet.
What is the boards opinion on fence post caps?
Necessary? Prevent rotting?

Anything you can do to limit the exposure of end grain to water will likely extend the life of the fence. That applies to both posts and pickets.

This. My next door neighbor put in an in-ground pool and installed an 8 ft. wooden fence around his property for privacy and insurance purposes.
The fence separates out properties and I see that 2 of his 6 x 6 posts have rotted badly, one so bad it is about 1/4 gone from absorbing water through end grain. They don't seem to make treated wood like they once did.

When it rains and splashes, it soaks the bottom end grain. Plus, some people keep their pickets way too close to the ground.

Treated wood is pretty much garbage now. I had ground contact expansion joints rot already in a driveway that was poured 3-4 years ago.

I'm getting ready to replace my outside stairs from the ground to the 2nd story back porch. It is exposed to the elements and I used 2 x 12 ground contact treated for the stringers and treated 2 x 4's for the stair treads----and that proved to be my big mistake. That allowed water to more easily penetrate the wood where the cuts were made for the risers and caused that to rot over the last 5 years to the point I need to replace them.
This time I will still use 2 x 12's for the risers and also use them for the treads themselves and will treat all cut areas with more wood preservative prior to securing the treads.
Live and learn.

Yes, do it. As someone mentioned, treated wood lasts half what it used to. I replaced all my decks ( one in front and 2 in back). I noticed the tops of posts growing fungus on some and black mold in some places after 4 years. I installed aluminum caps and then stained all of the decking. I used treated landscaping timbers to replace rotted railroad ties from likely decades ago before I owned the house. The timbers were rotting after 6 years and falling over. I pulled those out and went back in with railroad ties like I should have in the first place due to being in contact with the soil. Had a fence installed and I immediately stained it, but need to install caps on the 4x6 posts.
