Went in to order a 2022 Silverado 3500 CC, and of course can't get a confirmation due to the chip shortage. Anyways, wanted to hear from you guys on the good/bad so far on the 3500 Silverado platform with the 6.6 Gas motor, 3.73 axle, 159" WB

Posted (edited)

There are several recent threads that cover this subject.


I’ll sum up:

 

Bottom line is a bunch of us have bought the gas truck and are very happy with it. Meanwhile, the diesel guys tell us we should have bought the diesel.

I traded a duramax L5P in on my new 6.6 gas crew LWB.  I’ve put a couple thousand miles on it in a short time and am very happy so far.  
I don’t tow heavy (4-5k) and have put 5-6 hrs drive time towing also and was surprised that it actually tows better than my 17 6.0 with 4.10s.  I assumed the 3.73 would cause more shifting on inclines that it actually does, especially with the 37s I’m running.  
 

Whatever changes in programming that have been made to the 6sp tranny, coupled with the 6.6, make for a nice driving experience.  This truck is noticeably different/better than a 6.0 

 

Couldn’t tell you exactly what kind of mpg I’m getting-never cared enough to check but I’d bet it’s 12-13 unloaded mostly highway.  My duramax regularly got 14-15 per tank hand calculated on the same lift and tires.

Sorry Polaris1man if my attempt at humor delayed people responding to you. 
 

Regarding gas mileage, I get a little over 17 unloaded on the highway at 65 over low altitude rolling terrain. Running 70 plus drops it down to 16. I get about 15 with my pop-up slide-in truck camper that weighs about 1700 lbs and sticks up sbout 12 inches above the cab. I can’t offer any towing numbers yet. 
 

Like I said, I’m very happy with the gas engine and 6 spd transmission for my use, including some towing of an 8000 lb boat trailer.  
 

My only complaint about the truck is not engine specific:  the visibility to the front for off roading sucks because of the stupid “I drive a semi” high front end styling, and the giant mirrors seriously block the view of cross traffic and pedestrians at intersections. Even after four months if driving it I still occasionally slam on the brakes turning a corner because i see a car speeding at me from the right in my peripheral vision when really it’s a car passing behind me appearing in the huge mirror that blocks the front third of the passenger window.  I’m surprised the DOT allowed those  mirrors.  I’m hoping for an aftermarket mirror change, but not holding my breath.

The "drive a semi" high front end didn't bother me as much as for my wife, gonna need a couple of boat cushions for her!! I'm not too concerned about the mileage factor on the truck, just asking what to expect, guessing a 36 gallon tank will be enough to get one one Gas station to another.

Here is another question; any of you 6.6 Gaser's running aftermarket exhaust? GM recommends the Borla single, also been looking at the Flowmaster American Thunder duals, any thoughts?

Well, been watching the build of my '22 Silverado 3500, and now see it has left Flint MI via train and expect delivery around October 10th. Didn't go for the Denalli, hope to be happy with the LT model as I needed cloth seats for our 3 kids (Dogs) to avoid Leather scratching. Added 20" rims, tow mirrors, electric rear window, what ever tailgate with drop, running boards, bug shield, and a few other items. So does anyone have any news on the Cold Air Intakes and exhaust accessories?

    • I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps. 
    • Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.
    • 10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O. 
    • Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.    
    • apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
