  1. Tax evasion was probably his downfall. Selling vehicle mods shouldn't be a problem IF he labeled them as "Off-Road Use Only," with the usual disclaimer about violating existing laws.
  2. Has anyone experienced, or been denied, warranty repairs after your suspension mods? I have a 2021 Silverado Regular Cab, 4wd, Long Bed W/T. .....The tailgate and bed sides are much higher than my 1998 Silverado. .....Since I bought this as a work truck, it is a P.I.T.A. for loading & unloading anything. ....Although today's trend is to LIFT the trucks, I want to LOWER mine! GM warranty states that suspension mods void warranty. .....I'm concerned if I have non-suspension repairs needed (lifters, electronics, etc) GM could deny warranty repairs. A local Chevy dealer will sell you a new truck with a lift kit installed. ....From what I can learn, this is a "grey area" with warranty coverage. The risk of high-cost repairs if warranty is denied makes me nervous. I'm wishing I kept my 1998 Silverado!
  3. If this link works, it should take you to a list of many 2020 Silverado RPO codes. https://www.gmfleetorderguide.com/NASApp/domestic/rpocodes.jsp?year=2020&regionID=1&lang=1&divisionID=1&vehicleID=21795
  4. The QR code on the door pillar is limited to approx 48 RPO codes. ....To see ALL the codes installed, you need to obtain a copy of the Build Sheet for your truck using your VIN. .....You can get that from any friendly(?) Chevy dealer at no cost. ....It was available online for free, but now costs $50. The dealer accesses the Build Sheet through their GM-Global network online. Apparently, if you don't have RPO FHS, than you do not have Flex-Fuel (E85). This is for 2020: FHS E85 FlexFuel capable of running on unleaded or up to 85% ethanol 1 - Requires (L82) 5.3L EcoTec3 V8 engine. Not available with (ZW9) pickup bed delete. L82 Engine, 5.3L EcoTec3 V8 with Active Fuel Management, (355 hp [265 kW] @ 5600 rpm, 383 lb-ft of torque [518 Nm] @ 4100 rpm
  5. Are you sure you don't have AFM or DFM? Which engine/trans combo do you have? ....Unless your build sheet specifies "without AFM or DFM," or has RPO YK9, you probably have AFM or DFM on a V8. The build sheet for my 2021 W/T does not show AFM as a separate code. ....My L82 RPO appears as "5.3L Ecotech3 V8 Engine with Active Fuel Management."
  6. I don't know if this is your problem, but what format are your music files? My 2021 with IOR radio will not play WMA files. ...I had to convert some of my music files to MP3 files.
  7. Correct! The soft tray liner lifts off. ...Underneath is a single 7mm hex screw to remove. ...Tray has 4 clips holding it in.
  8. New guy here, but maybe I can help. My recently purchased 2021 WT came with the IOR radio and crappy speakers. ...The radio does not have balance or fade controls, but does have a 3-band equalizer. ....Doing my research here, I learned I wasn't the only one to complain of the poor quality sound. I replaced the 6x9 door speakers with Kenwood KFC-6966S 3-way's ($60) and the sound is incredible with the factory radio. Falsely thinking I had dash speakers, I bought Kenwood KFC-X2C speakers ($80) for the front corners of the dash. ....Upon disassembly I found no front speakers, but I was surprised to see there was factory-installed wiring for the speakers present, so I installed the Kenwoods. ....They are a perfect fit. The IOR radio is powerful enough to power the 4 speakers. ...Sadly, without a balance/fade control, the small dash speakers drowned out the 6x9's. ....I am installing L-pads so I can adjust the volume of the dash speakers separately. ...This should allow balance/fade to be adjusted for the fronts. I have considered mounting speakers behind the seats, but don't feel I need them. ....There is plenty of power in the factory amp, and it will pump out LOTS of volume. Adding rear speakers without having balance/fade control is one step backward IMHO. Many of the songs on my USB flashdrives would not play, so I had to convert the WMA files to MP3 format. ....Apparently the IOR will not read WMA files.
  9. Hello, All -- New guy here. 2021 Silverado 1500 W/T I am trying to learn the best location to route a wire from under the dash to under the hood. ....The wire has an approx 5/16" diameter plug on the end (which can not be removed, cut or spliced). Any suggestions? ....I am not opposed to drilling a hole, but I don't want to cause any problems by hitting plenums, ducts, a/c, heater core, hoses, etc. I have read many of the other threads, but don't see any suggestions. ....Thanks for any help you can provide.
