I did a bunch of add-ons the first two weeks I owned my new 2019 Raptor. I added, AMP running boards, BakFlip Toneau cover, AutoStop eliminator, wheel well liners, bed mat, changed stock wheels to optional bead locks, added triple bumper lights, rear under seat storage, window tint, RappyGraphics, Pedal Commander, and lastly, I installed front base plates (towing connections) so I could tow the Raptor behind my motor home. Two items I had to custom make, a mount for the connections between the motor home and truck and an under dash bracket to hold a switch that tells me, in the motor home, when the truck brakes are being applied by the braking system which is activated by the motor home air brakes.
I made the bracket when I was recovering from an infection during knee replacement and had a port hanging out of my chest. It made it hard to build a bracket under the dash and it came out crappy. Today, I dumped the bracket and designed a much nicer, simpler unit. It always feels good when you do something, sometimes in a rush, and then redesign a better product later.
