Okay, so I just read the owners manual for the 2023 GMC Sierra 1500 (stock) and on page 74 there is a caution section that says don't drive through stand water that is higher than the hubs. I measure that height at the rear tires and taking what the manual cautioned into account approximate fording/wadding depth is 16" at the center of the hub; so most likely 14" to 15" is a good conservative guess at what is safe for similar trucks that are in unaltered factory condition.
