Same. Interested in this aftermarket tank.

So to get back on topic, a 275/60/20 tires will not fit a non-AT4 Sierra 1500 (or a Sierra 1500 with no lift)? I ask because Michelin now makes a Defender LTX M/S2 in 275/65/20 that is a SL/XL load range tire.

Has anyone fit an H8 size battery into their non Duramax Silverado/Sierra 1500?

20" wheels and highway all season 275/60/20 tires are a bit heavier but not by that much that you would get 1-2 mpg worse. You usually hear about significant fuel economy impacts because someone's going with a significantly larger wheel/tire setup compared to factory along with AT or MT tread patterns which are not fuel efficient. There was a thread on the F150 forums where someone mounted a slightly larger Load Range E tire 275/65/20 and compared the fuel economy to the factory setup and it's really not that much different: https://www.f150gen14.com/forum/threads/apples-to-apples-efficiency-comparison-factory-33s-vs-lt-34s-tires-fixed-course.19977/#post-386490

Would turning off the CELs prevent someone's vehicle from passing OBD2 style emissions test?

The 20" wheel/tire combo should weigh less than the 22" wheel/tire combo provided they have the same overall diameter. AT tires will ride a bit rougher and weigh slightly more than a touring/highway all season tire, but it usually not too much more than a tour/highway all season tire unless you mount a Load Range E AT tire.

I know the AT3W and AT4W have the 3PMSF rating, but all else equal, a really good all season touring tire like the Michelin Defender LTX M/S2 should still outperform an AT tire in the snow/ice on packed surfaces like roads.

We test drove an SLT 1500 with 20" wheels/tires and a Denali with ARC and 22 inch wheels/tires. ARC can't make up for the extra harshness of the 22 inch wheels/tires not having enough sidewall to absorb potholes.

Did the dealer diagnose the issue? What was the root cause?

It also depends on what type of LRE tires. Heavy AT LRE tires will ride rougher than a Michelin Defender LTX M/S2 LRE tire.

Aren't these lifter failures getting expensive for GM?

This is one of the considerations of why I might go with a 1 ton HD SRW gas for trailering a track car on a tilt bed trailer. At 6,000 to 7,000 lbs and 25 % of it on the hitch, I can probably get away without using a WDH. That's a significant reduction in time required to hitch up on a Sunday afternoon as we finish up at the track.

+1. There are only a handful of reputable GM or Ford dealers that have significant internet sales volume. I'm not going to be taking my chances with other small time dealers that have no internet/forum presence or reputation if I have to fly there.

I've noticed this as well. I may just end up purchasing a 1/2 ton pickup in the next 12 months and letting GM/Ford resolve their lack of full size SUV production in the next 2-4 years.

The biggest difference, in my opinion, is the ordering process. Your order, practically speaking, enters the national build queue almost immediately. It's not so much based on each individual dealer's allocation. Therefore, delivery times are way more predictable for Ford. If someone else across the national is experiencing a delay or a constraint, it's probably similar for everyone.
