  1. Good write up. You're right regarding disconnecting the battery after you put the truck in mx mode.
  2. Consider not only the tongue weight of the trailer but the cargo going in the bed and the way to the passengers. Also consider where the water is going in the trailer sometimes if it's built correctly they put it right over the axle and other times they put forward of the axle so traveling full may really hurt you. You will probably be maxed out as far as your GVWR is concerned. With a weight distributing hitch you should be able to stay below all of your limits. On the surface that sounds like an easy tow. Just be aware that has tongue weight goes up these trucks porpoise like crazy
  3. An alternative, if it is close by to you and your need isn't too frequent, is just to rent a heavy duty truck from Enterprise Truck whenever you need it. You can specify gas diesel short bed long bed even make and model if you give them enough time. No need to worry about ad valorem taxes, maintenance or warranty. The biggest limitation is it has to be a bumper pull.
  4. Bought my 20 AT4 Carbon pro for 62k (66k MSRP) in August of 20. Optioned out the exact truck I have and it's almost 81K for a 23. wtf this is crazy.
  5. I have the same slop...it's been basically the same on my 07, 14 and 20. Vibrating the shifter though could be caused by tires or practically anything in the driveline. Heck even a busted tranny mount could allow for enough movement for the linkage to do strange things.
  6. If you know the max speed of the shaft you can use this formula I found on another site: MPH = (Driveshaft rpm * tire diameter in Inches ) / ( Gear Ratio * 336) Using the gm accessory steel shaft as an example on my truck: (4391*33.2)/(3.23*336)=134.32mph
  7. Deaver makes a kit for these trucks that replaces the overload spring with a progressive pack. Are you running loaded? Is your bump stop hitting the axle? That's a hell of a bump on a highway to bottom your suspension.
  8. Guess I learned something new. Wouldn't have thought they would remove the TB to clean vs using upper intake cleaner. I've never cleaned my TB...just use top tier fuel and the right oil. Glad you got it sorted.
  9. That is weird. hard to believe a cold air intake tube...wait....relearn what? There have been people who upgraded to the GM cold air intake and failed to get the calibration for the MAF complete and had all kinds of drivability issues.
  10. Just purchased a 6100 sq ft house and first time fill is $2.19/gal. Effective rate after fees is $2.22. All other fills are at 2.99 this year. Just found tank farm which is advertising $1.70 this year for my area.
  11. Other than being more resistant to impacts is there a benefit to the new driveshaft upgrade?
  12. I am on my third roll-x..well now it's called BAK Revolver X4S Tonneau Cover... IMO they provide a good balance of security, water tight and visibility out back window if you don't have the camera mirror. I get a little water intrusion at back by the tailgate but I haven't been worried about it.
  13. I tend to agree with Tim with it being electrical. Set your ebrake and have someone exercise the vehicle a little while you observe under the hood. Could be simple chafing on a harness that moves ever so slightly when you shift into different positions. Might also consider just letting it idle in park ebrake set and crawl under the truck moving harnesses by hand. Any kind of harness issue could cause a communications issue that results in a stall. Still under warranty?
  14. That sounds very similar but more intense than what I experienced as I could only hear the noise outside the truck. I take it with belts and pullies being replaced the dealer has isolated this to the engine bay and not the transmission bellhousing area?
  15. Couldn't play your video. Can you replicate by brake torquing the motor a little?
