Flooring for pier and beam house?

[Jeremy Horton]

Is there a specific type of flooring you all like to use on a pier and beam house?

Tile - I'm sure would crack over time 

LVP - Seems there can be an issue with the moisture barrier. Sounds like the moisture barrier can trap water beneath the floor and the wood foundation 

Carpet - definitely not 

Wood - waterproof or engineered - may be the go to - slightly more expensive but would match the rest of the house

My other properties all have slabs - so I've traditionally gone with either LVP or stained cement. There's definitely a few things to learn with a pier and beam type house

Quote from @Jeremy Horton:

The difference is that over a 2nd story there is no moisture beneath the flooring because the 1st floor ceiling is directly below you. Whereas on a pier and beam foundation you have the ground directly beneath the foundation. So there is a difference in the moisture content beneath the flooring. You don't want to trap this moisture beneath your floor and cause the wood foundation to rot

 Even if you're directly above the ground/crawlspace, your wooden subfloor (and joists for that matter) should not have a significant moisture content. If they do, they will rot, regardless of what flooring you place on top of them. 

I'll admit I'm not an expert on pier and beam (most AZ houses are slab on grade, too), but  if you're having moisture issues in the crawlspace you need to make sure it's either properly ventilated or sealed and dehumidified. If you have so much moisture down there that it's escaping through your wood subfloor and affecting your flooring choices, then you have too much moisture to begin with.
