I get the frustration, but I was explaining why Toyota made the decisions that they did. In the rest of the world you can't or can't easily buy an inline 6 Cummins diesel 3/4 or 1 ton truck. In North America, it's possible, and they're everywhere. Such a vehicle matches exactly the HD specs and HD use factor with just as many Cummins diesels working over 300,000 miles as any other vehicle type in heinous oil field, mining, line maintenance and other environments that are as brutal on vehicles as anywhere else, and it's all done for way less than the cost of a Land Cruiser at least in North America.
I see you drive a Ram Power Wagon, so you've already got about as good as HD vehicle as any in the world. The HD Land Cruiser simply could not and did not compete in North America so it got canned. Want HD, buy an HD truck, which you already have. Want $90K luxury SUV, why buy a Toyota when there's Porsche, Range Rover, G class, etc.
There's almost no way to buy a Power Wagon or Cummins diesel truck in the rest of the world, so 70 series and other HD Land Cruisers dominate those markets.
Toyota does not care about a few thousand enthusiasts in North America enough to go through the hassle of selling 1/100th the volume of 300 series Land Cruisers to HD trucks from domestic brands. I disagree that this decision will ruin the brand. Toyota is known for the 4Runner, Tacoma, Camry, Highlander, and Prius by far more loyal Toyota buyers in North America than a few (and it is very few) Land Cruiser buyers. Ford alone sells 80% more F series trucks in a quarter than Toyota sells Tundras in an entire year. Toyota is not an HD player in North America and the numbers of their vehicle sales clearly show that.
The Bronco sells to "enthusiasts" but not Overlanding Enthusiasts. It's marketed towards those enthusiasts that want 35 or 37" or bigger tires to drive over rocks for the sake of driving over big rocks. If you want the HD lots of miles, lots of payload (the Bronco's payload and towing capacity is the same as a minivan for crying out loud) that's why Ford will sell you an F250 or F250 Tremor for way less than the cost of a 200 series or a new Grenadier.
It's not that I have anything against Toyota or the Land Cruiser. As close to my ideal vehicle in the world is the 300 series in a 1958 edition trim, but I understand why I will never see that in North America. And, I am thankful for all the other options including the 250 series from both Ford and Toyota. See what I did there...anyway. Back to work.
