Rear of print bed always lower than front

Hey, I've got a VCore V3.1 - 500 and have struggled for a while with the rear of the bed being lower which is causing issues setting a Z-Offset. (Front always too close, Rear always too far if set in the middle) The bed mesh isn't too bad with around a 0.4mm range, and it would appear as though the mesh is compensating correctly as the rear side with the rear center peak is being corrected. However, it seems to consistently drop by around 0.3mm from front to back as if the bed is tilted backward. Looking at the bed mesh I'm assuming this is related to the way the Z Tilt is being performed on that high spot as the mesh seems to show all high spots around Z0/Z1/Z3, presumably due to a bowing/heavy bed. Before I spend another few days adjusting configs and re-testing, any ideas on the cause or the best way to adjust for this? Thanks ❤️
