  1. Yep, I have it on order. Thanks for the tip.
  2. I am the latest victim of the leaking rear window in my 2019 AT4 with rear slider. It must have been leaking for some time now and took out whatever that control module is behind the backseat. The dealership is fixing the leaking window for free since its a known defect and my warranty is replacing the module. I have been getting several service lights come on when its wet outside. Hope they get it fixed the first time. They did say they have fixed several with leaking windows so I hope they figured out the proper fix.
  3. Dealer called and said I have a leaking back window that is leaking onto the control module or whatever is behind the backseat. I hope this fixes the issue. They are going to replace the module and fix the leaking window. They should have it done in a couple days when the part comes in. I will update when I get it back.
  4. Yours sounds like a lifter issue. That is my guess. Mine is running perfect outside of the errors I already stated. Good luck.
  5. This is the second time these waring messages have come on now. Both times it has been wet roads. When you shut the truck off the E-brake will engage and when you try to restart it nothing happens, all lights just turn off when you try to push the start button. I had to disconnect the negative battery post for a few minutes and the error messages clear and it starts and runs like normal. Any body had this happen and what was the fix. I will be calling the dealer today to talk about this. I do have a Pulsar LT installed that I will be removing before I take it in. Not sure if that is the issue or not. I do remember having the service parking brake message come on before I installed the Pulsar. 2019 6.2 AT4 46,000 miles. No misfires and runs smooth while the lights are on. Thanks for any help.
  6. I have a 2019 AT4 6.2 10 speed with Pulsar LT and have not had any really issues. I did have a couple weird warning lights at first but have not had any issues for almost a year now. I do plan to buy the OBDII to USB cable so I can keep the Pulsar updated at some point here just wish it was included with the price these cost.
  7. I am using SuperSprings. They are like adding a leaf spring. They lift the rear end up and help with body roll. I tow about 8,000 lbs. all summer and winter. So far I am liking them. I did not notice any negative ride quality while not towing.
  8. I went up to a 275/70 R18 Load E Duratracs. The noise is about the same as the stock duratracs. No rubbing at all. I did notice a hit in MPGs with is to be expected with a heavier taller tire. I have no complaints and they are wearing just fine. Key to good wear on theses tires is rotations. I rotate every 5,000 miles.
  9. Michelin LTX M/S2 are a great tire. Quite and good rain/snow traction. Good life span too.
  10. This is what I did. Mounted them with 3M Auto Double sided tape. Sorry for the salt, got to love MN winters.
  11. I have the B&W tow and stow and it will still hit the tailgate when in the stow position. Best option is to get one of the hitch override switches so you can not lower the step part of the multi pro tailgate when a hitch is installed.
  12. I've had a 6.2 since my 2014 I bought brand new and now a 2019 6.2 in Feb. I am so used to the power when I get in my wife's car, which is not very often I drive it, I get that omg move car move feeling when I drive hers. I feel like I have to Fred Flintstone the thing to get it moving. I love the power when pull my 8,000 lb fish house/camper. I will always have the bigger motor. It fits my needs very well.
  13. Had 107,000 on my 2014 6.2 with little issues before I traded it in on a 2019 6.2. Got 32000 on the 2019
  14. 2019 6.2 10 speed 3.23 gears. Pulling my fish house / camper around 7500 lbs loaded with about 500lbs of gear in the bed. I have been getting about 8.2mpg. That is my 2014 6.2 6 speed 3.2 gears in the pics which I also got around 8mpg. Most trips I put on about 600 miles round trip.
