Mesh heightmap after three hours of adjusting.
Guess I don't know which corners to adjust which way. Watched the video 3 times. As often happens, the experts make it look easy.

Probably this one. It's linked in the FAQ in the Fix My Mesh section

I actually have the same map at the moment after a few hours and it's actually an improvement from where I was. Make sure you are running the Z-tilt after each adjustment before making another map. I forgot to do that a few times along the way.

I am at .465 at the moment, I will add that the box the bed was shipped in did have some shipping damage and it looks like something fell or was pushed into it. It had a s chip gash on the backside.

Yeah, I've got the same problem, watched the same video, & spent an entire day trying to straighten it out. No luck. Today, I saw a video of a guy using a different approach: instead of screwing around with the frame, he used shims under his flex plate. Are you using a flex plate?
I’ve tried the shims too. I’ve been looking for a video on skew calibration but haven’t found one yet.

If you’re able to print things, try some screw jacks off printables to help you make fine adjustments. It’s very difficult to move the extrusions small amounts accurately, and those small amounts translate to big distances of the width of the bed. I also used sticky markers on the side of the frame to try and make things easier.
It can be a frustrating process — sometimes it’s best to walk away and come back later.
From looking at it, seems you have some bow in your gantry and some twist in your frame... Not uncommon stuff really
