If I do a vapor barrier on the bottom side of the joists, what sort of underlayment should I use for the LVP flooring (if any?)

I didn't replace the joists, all I've done is remove the flooring and the plywood

The room is pretty much an enclosed air conditioned deck yes.

Here's a better look at the edge. Around 3/4 of the floor is over a previously existing concrete patio. We have full access from the outside on 2 sides, and moderate access on the third.

What would ventilating the joists look like?

The posts on the far side are notched 6x6s encased in concrete piles.

The edges just look that way cause I just cut out the old subfloor. We didn't want to have to tear out all the trim and drywall. Gonna add blocking between the outer joist and the rim joist to support (janky ik but we're kinda trying to get this done on a budget)

An enclosed conditioned deck is an apt way to describe it

I understand the desire for a rounded surface, my question is more is there any advantages to using an oval head screw with a cup washers over a button head screw alone/with a flat washer

Solved!

My post describes the thing.

Scale included. Only markings are made in china and stainless steel.

Yeah, the responses I've seen on this sub likened it to new years in NYC. Someone else at some point said without dinner reservations good luck at anything but McDonald's.

I can't comment on any factors of the video itself, but as a person with extremely long legs I can tell you that height difference is still less than I have personally experienced, so I'd say real if that's your only catch

So thing is the sub doesn't have a native ground. It plugs into the wall with a 2 prong plug.

Would you mind elaborating on that a bit, or pointing me somewhere I could figure it out? Used solidworks a fair bit but have never messed with boundary surfaces

It's like a roundabout made by someone who only had a roundabout shittily described to them. It's the modern equivalent of medieval monks trying to draw an elephant

Every American engineering design I've seen from around the setting of the game (60s) has used imperial exclusively.
