How much pin box flex is OK?

The other day I thought the pinbox was flexing when we hitched the trailer to the truck.

Today I put a piece of tape on the frame to see how much it was moving. When the weight is on the pinbox the front bolt hole in the frame moves up about 1/8" in relation to the bottom of the trailer. Is this considered normal?

1/8” isn’t that much. I’ve seen much more, keep an eye on it but I think your within normal limits.
