Ford Pro Trailer Backup Assist Module

[ScottN]

I recently took delivery of a 2022 Ford F350 SRW and a 2022 Montana 3121RL. The truck has Pro Trailer Backup Assist (PTBA) with a sensing module. There is not a large enough flat surface on the outside of the Lippert Road Armor "Trailair" hitch that would allow the use of the mounting straps (large wire ties), or the adhesive-backed bracket (see attached picture). I am looking for suggestions on where to mount the PTBA module. If there is a flat surface inside the hitch, can the module go there?
