V6 Silverados

Is it the 4.3 Typhoon/Cyclone V6?

Ditto. I wouldn't even consider a 5.3 to tow a 9000lb trailer, nor a 1500!

I was going off the vin number lookup function in the camping world towing guide (https://rv.campingworld.com/towguide) For example, vin # 1GCRWBEH3MZ116570 is a 2021 Silverado 1500 Custom with the 4.3L V6. Enter that vin and it returns a tow limit of 9700. If you enter vin 1GCUYDED1MZ106911 which is a 2021 Silverado LT with the 5.3L V8, it returns 9000 or 9100 depending on bed length. Reason I'm asking is the price difference is HUGE.

The tow guide is incorrect. The V6 highest tow rating is 7900. That is a regular cab truck. 7400 lbs for the crew and double cab.

Also, the custom trim is much cheaper than the LT. Make sure you check out the custom to ensure it meets your needs. The LT comes with options that I definitely want in my truck.

When I hear questions like this I think back to my 1991 F250 with the most powerful engine sold by anyone that year for trailer towing, 230hp. The current 4.3l is 285hp. I often went over 10,000lbs with 230hp and go everywhere I needed to go, and that was with a 4 speed transmission.

I could go farther back to a 1978 Chrysler that with towing package was rated for around 7,000lbs with 150hp. Again, the most powerful engine available for trailer towing that year. That was a huge step up from the 1966 Rambler with a 232 cubic inch 6 cylinder that we used for a while to pull trailers.

I feel sure that you could get there with 285hp. The engine will rev a little higher but it is not nearly as noticeable in the new engines. It just depends on how big of hurry you are in and how often you do it.

I may have towed a 9500lb travel trailer 55 miles in Michigan to a campground with elevation increase of 300 ft. If I did do this, I did get there.;)

Not a fair comparasion, you switched to a diesel.:E

OK, point taken. Although Porsche then used a production Cayenne Turbo S to successfully pull the same A380. I don't know what's more expensive? The A380 or the Turbo S? :B

Not meaning to go off-topic, but wondering how do manufacturers actually determine vehicle rated towing capacity? Since many can physically tow more?

Yes, it most certainly can.

Of course you must be going downhill only.

Can the new Chevy Silverados with the 4.3L V6 really how over 9000 pounds? Anyone with practical experience in one case to arrest to that?

I'm not sure where that number comes from, because with that engine the max towing is 7800 lbs. GCWR is 12,800, which sounds reasonable for the hp/torque of that motor. With a truck GVWR of 7000ish, a GCWR of 12,800 gives a realistic towing capacity of 6000 lbs or so. Interestingly, the 2.7 turbo 4 has a significantly higher towing capacity, and with its far superior low end torque would make a much better towing motor. If I were in the market for a GM 1500 series truck I would consider that motor even over the 5.3 V8.

Go with this motor, ie the I4 over the V6. 8 sp trans with a 4.3-1 1st gear vs 6sp and 4.10 behind v6. Get a 3.42 AR, 3.73 might be available. A bit more HP, torque, and a turbo so when at elevations, you do not lose HP.
This is where Ive been toying with going vs the 6 to tote my 6500 lb trailer about. Then again, I have my MDT.....so do not truly need a big truck per say.

Either rig for the most part, unless loaded with options, has around 1800-2000 lbs of payload. So with two people, lightly loaded otherwise in truck, 10-12% HW. 9000 lbs is doable. Probably not super fun. I try to do no more than 2x the GRAW, at 3900 for GM's, that puts you at around 8000 lbs.

My 02 not that its worth much!
