Just talked with Underland Offroad - they said to use the link here to measure the back wall on the V2 Pro and send them the measurements - the V2 Pro measurements apparently changed a bit from the V2 with regards to the fit of the Molle Panel. I have the V2 Pro getting installed next week (week of 8/26/2024) on a F250 SuperDuty with 8’ bed. https://cdn.shopify.com/s/files/1/0195/3434/8352/files/ULO_GFC_Measurements.pdf?v=1687988026
