solo Nationals is coming up, which means a 3000-mile roundtrip tow, which means it's truck tuneup season. This weekend my 130,000-mile 2010 Tundra gets oil, filter, brake pads, spark plugs, wipers, maybe a carrier bearing an u-joint if they're clunky, and these:
Although the truck is rated to tow over 10,000 lbs, it sags like crazy with any meaningful tongue weight, even with a load leveling hitch. I added some helper springs, but I've always wanted to have a little more insurance to correct ride height in the rear.
The problem is, I'm cheap, and airbag kits are like $600+.
But, come on, they're bags that hold air. What's so complicated? I found this set on some corner of the internet for $179, which was the lowest price I could find for a set of application-specific bags for my Tundra. I'm installing them this weekend with all my other maintenance.
So, what's the hive's over/under on whether they're any good or not? My prediction is that the bags themselves are probably fine, the hardware is probably a little substandard and I'll be going to my hardware shelf for a few nicer fasteners, and that I may be going to the hardware store for an air fitting or two (either because the supplied ones are junk or because i want to route things differently than they want me to).
What does the board say?
No specific knowledge of this brand, but I did put bags on my Astro for all the same reasons you cite and they worked like a charm. The hoses and fittings didn't take well to our salted roads, but the bags worked well for many years. They made trailer towing much, much better.
Worst case and they blow, take some measurements off the bags and order a set of Firestone bags the same size.
Not just True but ReTrue!
With a name like that, they have to be good.
You could go even cheaper...
If it's a helper air bag and doesn't replace any springs, I wouldn't worry too much.

I'm pretty impressed with the number of different sports represented here.
If you haven't already replaced your shocks you might as well just go ahead and start looking for better ones now. I expect that these airbags will work fine but will make everything feel underdamped.

It's got a pretty dope set of Eibach dampers on it, which definitely improved every facet of its manners.
Will you die? Absolutely, unless you've found De Leon's fountain of youth. Will you die from these airbags? Time will tell but probably not.
My BIL tows with a Tundra, and I can echo your exact sentiment. Even with helper leaves on it, it sags like crazy.
Interested to hear how your airbags help
I thought this was going to be about Takata air bags. These look a lot safer.
Use them until they don't work anymore.
All that is lost is a little time and money.
Is there an installation story coming up with these? You might as well get paid to put them on. 
I use my dad's 2017 Tundra for towing long distance and have noticed it sags. Nocones thought we had too much tongue weight when he first saw it. But what does that guy know!? (
) Something to make it simplier to level the load would be nice. I look forward to watching this go together.
I have some random brand of airbags from Amazon on my offroad 91 Toyota 4x4
Granted, it's a custom decoupled setup used to help with support when it has a load, but still allow complete travel. Uses a poly cup on the leaf spring.
That said, the bags have been on there since 2019 on a vehicle that's often in a very rough environment and gets stored outside. If my experience is any indicator, the bags will be fine
