Good evening. Saw your posts on adding the front Park Assist rig. Have a '20 2500 Tradesman that appears to be similar in factory options to yours, and would like to add Park Assist as well as a few other things. Had an unsuccessful/expensive attempt to add the trailer TPMS, and was wondering if you would you mind if I asked a few questions before I invest in the PA hardware. Really appreciate your posts! - Aaron
