LOL Anytime my friend: Would be amazing if forum members were close to here.
My wife keeps asking what I intend to do with so much alcohol in the next home where will certainly not have a bar this size; I said I'll probably invite all the neighbors for a BBQ and drinks party and have a free whiskey stand in the driveway (perhaps not, may get arrested for that). At our realtors request, for the photo shoot and sale, almost 70% of previously displayed alcohol at the bar, has been removed and packed. Wife and I are consuming all white and rose wines over weekends; dunno what I'm gonna do with my fine red wine collection, where a large quantity is already packed.

I'll send a shipping label for any unwanted "fine red wine" in the collection

Went to the truck stop and filled my def. It was down to 1 bar on the dash. I honestly forget about it most of the time since it doesn't use much at all. Actually, my wife was the one to remind me to check it this weekend. I've been averaging almost a 5k oil change with def fill ups.

Well guys after months and months of debating and researching on this site and others, today I pulled the trigger on tire size and brand. Went with the Toyo AT3 in a 285/60/20 size on my completely stock 2022.5 AT4 6.2L. Zero rub in either direction at full lock. The most important thing about this tire to me was the fact that it came in a P-Rated (Standard Load) version, which means that it is 20lb lighter PER tire than the other brands which only offer the E-Load in this size. Which means hopefully I keep my gas mileage and get up and go. Very happy with the look and how quiet they are so far!

Great looking tire! I'd be interesting in knowing how they perform in the rain for you.

Rotated the tires in the driveway yesterday. Then ran her up to Firestone for the alignment. She was only off a little, but I was noticing that the front drivers tire was starting to wear a bit on the outside.

Installed a Borla ATAK, Puddle Lights on when conditions are met, and Venom Tks Full time Amber DRL's.

Did you install the entire ATAK system or the LS Crate muffler?
