    2017 Silverado LT Z71 5.3 3.42 DC
  1. Thanks for all the replies. I am not maxing out any of the capabilities so it looks like my initial thinking was in the ballpark for most of the opinions. A little extra psi in the rear might be OK, but not necessarily needed. I thought CDNSS's comments/experience were very interesting. When I actually get to tow I will monitor the tire temps, (along with the trailer brake and tire temps). If a 3 or 4psi extra lowers the temps I will probably run that. Can't imagine running more than 5 psi over the door sticker for my situation. Thanks all.
  2. Hello all Just got a new travel trailer and will start towing this spring. My question is about tire pressure for the Silverado when towing. I will have close to 600lbs tongue weight, very little if any bed weight, and a good WD/Sway control hitch. Truck is stock as far as suspension and tires. Have the 265/65R18 Goodyear Fortitude on the Z71. Sticker says 35psi. I usually run 33 in the rear because I am usually empty or close to empty. Max pressure on the sidewall is 51. Manual says 35 is the minimum for the load truck is designed to carry. I will be significantly below GCWR and GVWR, but significant none the less towing about 5k. I am leaning to starting out with something in the 35-40 psi range in the rears, but wanted to see if there was any kind of consensus on something different. Looking for it all, most stable ride and tire life. Thanks
  3. I just use a NanoVault 300 under the passenger seat attached to seat frame with the included cable. Out of site, I can reach from drivers seat, no key and I can take it out into a hotel room or airplane (TSA approved) if needed. It is a deterrent, not a full blown secure safe, but works for my needs if I end up somewhere I cant carry. It is small enough to fit in console if you wanted to secure in there some way. Good luck
  4. Wanted to post about another successful tow mirror upgrade with pgamboas harnesses and mods to the 1AAuto tow mirrors. I know this thread is full of success stories, but I need to point out how much pgamboa went above and beyond for my install. Issues with the mirrors, that had nothing to do with his mods or my install, but he took it upon himself to get them all resolved. It took three sets, but eventually everything was taken care of and I have the mirrors and functions I wanted. I would have quit and gone a different route much sooner than pgmboa. He really stuck with it and got me all fixed up. Kudos and thanks.
  5. Were you using cruise control? It could have been the grade braking (engine braking) that the truck uses to attempt to maintain speed, not go too fast, on the down hills. It doesn't do this, or at least not to the same extent, when not in tow/haul. It will just let the truck go over the set speed.
  6. Thanks all. After being ready to listen to it when I opened the door this morning I do believe the buzzing I am hearing is the fuel pump. Only does it after sitting overnight. I will take it as nothing to worry about albeit a tad annoying.
  7. Hello all, Just picked up the new truck Monday so I don't have a lot of experience to explain what is happening. Each morning, two so far, when I opened the driver's door the first time of the day I heard a very audible 'buzz' that lasted about 1-1.5 seconds. It happens quick and unexpected, so far, so I haven't been able to place the source much. It is probably coming from outside the cab though. It is very audible. I thought maybe something with the EVAP or purge, but it happens when I open the door, not at key on or startup. Curious as much as worried. Any ideas? I park in a locked garage with the truck unlocked if that makes any difference. Has only happened after truck sits over night. Thanks On an unrelated note. Where is the external/aux transmission cooler on this model? My 2012 it was right behind the grill and very visible. Haven't found it on this 2017 yet. And yes I should have it and do have KNP code.
