There is a big difference between making a mistake and gross endangerment of others' lives.
This is correct. There's a big difference between personality traits ( who likes what brand of lube ...) and egregious, dangerous behavior.
I've been around RVs my entire life, even as a kid. There are people whom know what they are doing, and those who don't.
This is not the OPs fault; it's just his buddies rig and truck. But ....
This is darn dangerous, and should the unthinkable happen, there's going to be a BIG lawsuit. You think Toyota is going to say "Sure - we are fine if you ignore our towing and load limits. After all, we're just some multi-billion-dollar international company with deep pockets. We'll go ahead and cover the punitive damages from the jurors' award because this guy killed a family when his overloaded truck could not handle the situation and crushed the family."
You don't think accidents happen due to overloading? You don't think people are killed every day by overloaded and unsafe vehicles? I just had to deal with a multiple fatality last month where an overloaded class 5 truck could not stop in time, swerved and the load caused him to roll over onto a motorcycle at a stoplight.
The Tundra in this thread is dangerously overloaded. Can the engine pull the load? Yes. Can the engine do it and survive? Apparently so, because the wear is commendable.
Let's remember that the SAE introduced a new towing standard J2807 a few years ago so that fair, accurate, reliable comparisons and contrasts could be made for all vehicles intended to tow. I looked at Toyota's website and could not find any claim to the SAE standard, but I'm fairly sure all the major brands (GM, Ford, Ram, Toyota, Nissan) all use that standard for their truck tow ratings. Don't you think if Toyota could have the tundra tow/haul more, they would rate it higher? After all, the Toyota actually is way low on towing and hauling ratings contrasted to the Big 3. If Toyota states it's Tundra 4x4 towing limit is 8800 lbs, then that's what they mean. It sure as heck isn't anywhere close to 14,000 lbs like the rig we see in the picture! And adding air springs in the rear only levels the truck; it does NOT in any manner increase the load carrying limit.

Ford, for example, has their SAE call-out right on page two, at the bottom of their towing guide:

Toyota does not specify if they use the SAE standard (at least I could not find it ... but I may have overlooked it)

As you can clearly see, starting on page 170, they talk about weights, capacities, limits, etc. One thing that is not immediately obvious but is very critical is the max axle loading. Often will be stated on the vehicle ID label in the door jam. I suspect this example is WAY OVER the axle limits.
But there are times when the glaringly obvious needs to be addressed, and I hope the OP takes the opportunity to tell his buddy that the rest of the world does not appreciate him taking liberties with my family and all those around us. In this case, the off-topic is actually far more important than a boring UOA from a well-running engine.
