My updated list of mods:
Removed my AM/FM antenna whip Gives it a cleaner look and I don't really listen to AM or FM anyways.
I will be installing a "hidden antenna," or two, within the next couple weeks, will need them for my scanner and if I decide to listen to FM next time I'm in a BIG city, like San Diego, again. * Set my forward-facing white lights to all be on with my high beams. ($1.98 for two diodes, used on for this mod) On the '15 Silverado, the lows stay on with the high beams, and the diode was set to turn on my fogs. * Set my rear-facing white lights to all be on with my reverse lights, with the other diode from the 2 pack mentioned above, cargo lights come on with my reverse lights.
2 & 3 both took 30-45 minutes of my time to accomplish (once I had the diodes), including operational checkouts, worth it.
Mounted my CB antenna on the front right stake hole (about $40 invested in parts for my previous truck & $80 for the handheld router, that was not needed).
Tow hitch brake light - modified it to only light up when the brakes are applied. $20 for the light assy ($17 on etrailer.com, Item #CR-007A) & couple of hours of research to cut the correct wire. Did this one today, need to make sure that you have the tail/brake light that has the little box on it to keep the blinkers from flashing the hitch light. Took me about 3 minutes to cut the brown wire (tail light) at both ends (at the plug and up by the bulb housing) completely remove it, and throw it away.
Shortly after I bought my truck, I had to go buy a 4-wire extension, so I could plug it in, less than $10. (didn't need this on my last truck, connectors were right next to the receiver) *** Just went outside, with my son, and performed an operational check on it. Works great. *** Lock/Unlock visual indicators use all four corners, including brake lights (not the one on top of the cab. Turned on parking lights and head lights, hitch light did not light up. Pressed the brake, hitch light works. Used turn signals and hazards, hitch light did not work. Magnetic Phone holder (#5) - completed this one before Thanksgiving, found a Steelie vent mount for about $20. Only downside to this one, and having vertical vents, is during every turn and curve, the weight of the phone swings the vent toward the outside of the turn. If I turn right, the phone swings left, and vise verse. * Better phone holder – recently purchased a windshield phone holder, going to modify it to fit in the pocket left of the steering wheel and run power to it. Believe I saw this one within this thread. Thanks for all of the information and writeup, Waymon. Frame plugs. I'm going to do this one after I get my truck washed and all of the residual dirt flushed out of the tubes. Went off-roading a few weeks back and the dirt still has not “blown out” from driving around. * Cutting a 2”x12” to fit across the bed of my truck, for cargo management. Cut to 65” and trim as necessary.
45° two adjacent corners along one long side, so it sits down against the bed of the truck. PlastiDip it black when it is trimmed to fit. Window tint across top 4-5" of windshield, down even with the lane departure camera housing. Should cost less than $30. Black bow ties, front/back/steering wheel, and contemplating blacking out the middle of the “Z”s and the “71”s. Should be done in next week or two. Philips LED reverse & cargo lights. K&N Air & Cabin Filters. Bed rail lighting - Spent about $35 for everything so far. Front Tow Hitch - found a hitch for $50 and was hoping to install it over my Christmas break from work, 9 paid days off, but we ended up traveling and seeing family during that time. One of these weekends, I'll get around to this.
* - Low cost mod discovered/found after posting my plan list.
