    2018 GMC Sierra SLT 5.3/8L90/3.42 - Red Quartz Tricoat
  1. There's no way in the world I'd borrow that kind of money on a 3 year old truck with no bumper to bumper warranty and <2 years of powertrain warranty left. Is this one of those buy-here, pay-here type places? If so, RUN!
  2. I would think the trailer would have an onboard charger wired to the 120v shore power. If so, make sure it works and keep the trailer plugged in. Just don't forget to keep the trailer deep cycle battery topped up with DISTILLED water.
  3. Do other 12v items in the trailer work? Are we sure the jack still works. Maybe turn the truck around and run jumper cables from the truck batt to the trailer house batt the try the jack. If it doesn't work then, then you know you've either got a problem with the jack or it's connection to the trailer battery.
  4. Unlike my 08, my 18 came from the factory with the +12v pin on the 7way plug hot already. Look up the pinout for a 7way plug and use a multimeter or test light to see if you've even got power at the plug. Is the deep cycle battery in the RV good? If it's toast, it will suck all the amps that the plug can provide leaving nothing for the jack. The jack should be running off the RV house battery in the first place, not directly off the plug. You shouldn't even need to plug in to use the jack. EDIT: just realized it may not be an RV. A trailer big enough to need an electric jack likely has electric brakes. If so it should have a battery and a breakaway system to energize the brakes in the event of the trailer coming off the hitch.
  5. Same diameter wheels on both trucks? I'd imagine 22's would be pretty bone-jarring in any case. Only other difference I can think of would be the magnetic shocks in the Denali.
  6. Can't burnout

    Not crabby patties, just old farts that were once young and did the same silly stuff and broke parts in the process. In my case, blew the carrier of a 10 bolt G80 apart at 72000 miles in a 98 k1500 If you absolutely must do so. 1) With the engine running, press AND HOLD the traction control button until not only it says "Traction Control Off" in the DIC, keep holding the button until it says stabilitrack off. 2)Put the truck all the way down in 1st gear. 3) Left foot on the brake, right foot has the accelerator on the floorboard.Press hard on the brake, but just hard enough for the front brakes to hold the truck in place. The rear tires should begin to spin slowly and then speed up as they get hot. If you still can't get them to break loose, then armor-all on the tire treads should get them started. Just make sure you burn it all off before you try to drive somewhere. I advise you to do none of this. It endangers you, your trucks drivetrain, and bystanders. That being said, have a happy Independence Day.
  7. Can't burnout

    You're gonna tear up your truck. The 4-speed 4L60E transmission and 8.8" 10-bolt G80 rear end you have will not stand up to repeated brake stands (power braking) over the long term.
  8. Black paint swirls

    Solid (non-metallic) colors, always seem to show swirls the worst. Namely black and red. They're there on white too, just harder to see. I'll never own another non-metallic paint vehicle.
  9. Throttle response

    If it's an 8-speed, just press the accelerator a bit harder and give it 500-600 miles. Somewhere around 550 miles, mine woke up and you no longer had to get into the throttle bigly to keep it from upshifting below 2k rpm.
  10. Suspension/lift issues

    Maybe call Rough Country. They were very helpful when I had a problem with the lift kit I put on my '98. Then again, that was close to 20 years ago so...
  11. Dyson customer since 2007. Terry Dyson is top notch and his advanced analysis kit (which has admittedly gone up on price over the years) is worth the money for the insight he can give you. If you email him with questions, he may very well be able to give you advice to use for BEFORE you have to send the sample in. Hope he can help you get your truck straightened out.
  12. Looking to upgrade after 10 years from my 08 GMC CC 4x4 5.3 4-speed SLT. Local dealer has a DEMO 18 Chevy LT 5.3 4x4 6-speed leather bench seats Allstar plus package with 3800 mi for just under 39k. 14k off sticker. Decent price?
  13. Water pump replacement

    Thermostat; while you're working on the pump it's cheap and easy to get to. Coolant reservoir pressure cap. Again, cheap insurance.
  14. Despite the identical RPO codes. 08 5.3 trucks didn't have variable cam phasing, which showed up in 5.3's in 2010. I'd talk to a tuner and see if the variable cam phasing issue can be worked around through tuning before I dropped the cash for a motor. I've got a hunch it may be a deal-breaker though.
