If it was built before Nov 15, it should be as ordered. If not, then heated rear seats won't be included if ordered -- and the option price will be off the invoice. Heated fronts never were available on base truck and still included on Denali. Note 1 -- applies to all other trims KA1 Seating, heated driver and front outboard passenger 1 - Vehicles built prior to 11-15-2021 include heated driver and front outboard passenger seats. Certain vehicles built on or after 11-15-2021 will be forced to include (00V) Not Equipped with Heated or Ventilated Front Seats, which removes heated front seats. See dealer for details or the window label for the features on a specific vehicle. Same sorta deal with the ventilated seats on the trims that normally have them available (and still included on Denali) 00V Not Equipped with Heated or Ventilated Front Seats, see dealer for details 1 - Certain vehicles built on or after 11-15-2021 will be forced to include (00V) Not Equipped with Heated or Ventilated Front Seats, which removes heated and ventilated front seats. 00V Note 1 -- applies to all trims except base and Denali (on base trim they were never available, Denali they are still included)

If a 1500 could do a 2500's job, they wouldn't need a 2500.... Buy whatever suits the task at hand.

You haven't said what your needs/wants are, but somehow a lifted 1500 custom and a 2500 6.6L both fit them. Be sure you compare all the features on each. Both those included on the trim level and the optional ones on the particular truck. Options can make a significant difference in the bottom line msrp. If your intending to keep it for at least 5 years, and if your not in a rush, check out the info on the 'refreshed' 2022 1500's that have been revealed and will be available in the spring. (the one you are looking at is a 2022 1500 LTD -- which is the same truck as the 2021.) The 2500's will get the refresh, but not at the same time as the 1500's. 6.2 requires premium fuel, 6.6 does not. 1500 will get better mileage. ( I realize you said fuel economy/costs aren't a big deal to you) Trailboss has the 2" factory lift -- and it's still not as tall as a stock 2500. If you don't want a tall truck, maybe a 1500 Custom (non Trailboss) is consideration -- but that would mean no 6.2L and no 10 speed, as the 1500 Custom would have the 2.7L Turbo engine with the 8 speed. I've gotten to where I find the extra height to be an annoyance rather than a benefit.

First question is what do you want to do with it? Loaded with stuff or just driver (and passenger(s)) Paved roads? Gravel roads? Mud? 2 track trails? Mall crawl? Freeway commuting? Rock crawl? Deep sand?

Every tire has a 'load vs inflation' pressure table. (if you change to a different tire size, it probably has a different recommended pressure for the trucks axle weights. The door sticker will have the pressure for when the truck is loaded and has tire size/load rating it was born with. Empty, the load is probably higher on the fronts than on the rears. Axle weights from a scale is a good idea. https://tirepressure.com/lt275-65r20-tire-pressure Tire Size 35 psi 40 psi 45 psi 50 psi 55 psi 60 psi 65 psi 70 psi 75 psi 80 psi 95 psi LT275/65R20 Single Tire 2080 lbs 2280 lbs 2475 lbs 2680 lbs 2850 lbs 3030 lbs 3195 lbs 3375 lbs 3540 lbs 3750 lbs (E) 126 LT275/65R20 Dual Tires 1895 lbs 2075 lbs 2250 lbs 2470 lbs 2595 lbs 2755 lbs 2910 lbs 3070 lbs 3220 lbs 3415 lbs (E) 123

In the other thread, he did say he wanted it to be loud and obnoxious...

Sorry if I mislead. I've had 4 of 6.6's (one at a time) -- 2004 LLY, 2010 LMM, 2011LML, 2018 L5P I have the 3.0 because my needs no longer require a 6.6. When the heavier jobs were done I tried 1500 8 speeds. A 6.2 (NHT was unavailable when I was having it built) and then a 5.3NHT. After years of running 6.6's I just couldn't get happy with the way the gassers drove. Pulling an enclosed utility trailer across the country with the NHT was the last straw and went to an '18 6.6. (even though the jobs for it didn't justify that much truck) 3.0 / 10 speed seemed to be what I'd been 'looking' for. I did order the 'standard bed' (so with the new body style, it's a little longer than the 2500 crew w/standard was. Imho, they've made the 2500's too high/tall for ease of use -- getting in/out and access to the box. A lifted 1500 (AT4 or either Trailboss) are still shorter than the 2500's.

6.6's can give good mileage, but not like the 3.0. Similar tasks, my 3.0L is running a little over 25 lifetime (1 year, 16,000 miles) vs the 6.6's which generally gave numbers high teens. Of course they all will show higher 'cruising down the highway' numbers. Above numbers tank averages. You'll love they way the 6.6 pulls! Congrats.

AT4 may have had optional mirrors available. In any case they could have been changed by the previous owner.

'Opportunity' during it's train ride?

You're not alone. Check out the 'crank / no start' threads. You can read til your eyes bleed. (including one that is in the HD truck section --- not sure why the mods haven't moved it out of that area) If it hasn't been to a dealer since early October there is an update that is intended to correct this issue. Some trucks it seems to be common, others never do it.

Just making sure, as it wasn't mentioned.

Not sure how this fits in with posters in this thread, but it's not just the vehicle side that needs to be wireless AA / CP capable. It's also necessary to have phone hardware capable of wireless AA or CP.

No doubt they know that some will own them for a very long time. Cancels out some of the the ones that trade every year.

Have you verified that the winter rims from you '111 will fit on your current truck? Some of the older ones will work, others the wheel spokes will interfere. (the diameter is not the problem -- the still use 17" and 18" )

The 6 changes the dealer is providing aren't 'free'. They are pre-paid. (and buried in the sales transaction)

What date was it in when that happened?

There is likely more than one thing that determines the speed limiter setting -- just as there is more than one thing that determines the payload rating and the tow rating. 20" tires shipped on my truck are S rated (door sticker shows this too) The optional R3O Tires, LT275/65R18C blackwall Goodyear Wrangler DuraTrac MT are Q speed rated

Some Duratrac sizes are 3PMSF, some are not.

Good to hear they can only be programmed to one.

Has it ever had a brake service? Check pads, lube slider pins...

If it's a reg cab diesel it has a 28 gallon. All other 21 3500's (gas and diesel, in any cab/box combo) have 36 gallon correction in post below

Yupp -- and newdude is trying to get the OP to verify that the part number/frequency for both sets of sensors. Some part listings show multiple part numbers for the years in question. Verifying what they are may help determine the solution -- and determine if the dealer is correct that new sensors are needed. No matter what tool is available, if the frequency of the sensors does not match the frequency of the vehicle they will not be able to be paired. Of course, this is why many tire shops use dual frequency sensors. Slightly higher sensor cost, but then it doesn't matter what the vehicle frequency is. Great convenience to the tire shop.
