Costco has a discount on their Honeywell (Generac) standby generators.
This deal includes the discount, which lines up with a Generac promo offering a free 10yr warranty.
There are three options from Costco:

18kw option for 4,399: 600 off w/10yr warranty:

14kw option for 3,799: 600 off w/ 10yr warranty:
https://www.costco.com/.product.4000145693.html
This purchase includes the generator unit and auto transfer switch (switch size dependent on model, some are 200a while the smaller one is 100a)
Price also includes threshold delivery (to your house, in the garage)
No installation included - that part is up to you or your contractor
Previous deal page for reference:
https://slickdeals.net/f/16110247-honeywell-22kw-home-standby-generator-with-automatic-200a-transfer-switch-plus-500-cash-card-4899-99-at-costco?src=SiteSearch
That deal was -500 but also included a $500 cash card but did not include the 10yr warranty. To add the warranty with purchase the price is over 1,000 - makes this deal on par or better than before.
To get the warranty, you must purchase by 10/8 and install/activate by 12/17.

Is it challenging to find someone to do this install after telling them you already have the generator?
I think the gas line might need to get enlarged since the house gas line originally was only sized for the stove/water heater/HVAC.
As for the DIY install - part of it is pretty straightforward, like getting the site ready or making the pad for it to sit on. The fuel and electrical hookups are the hardest part, but you can sub those out if you want.
These require annual servicing as well - oil and filter change. This can be done by authorized service or you can do it yourself. They will "exercise" on a schedule and report issues as well. Have been waiting on a deal, and jump when I saw the discount stacked with the warranty.
