I was at a dyno day yesterday, and there was a near new F-350 Powerstroke 6L diesel truck there. I happened to know the owner, and he pointed out something that just blew my mind. Notice the cut and taped wires with NO SEALANT OR COVERING OVER THE CUT ENDS!!!

It came like this from the factory. Someone in the audience went and checked his 05, and sure enough, it has the same cut and exposed wires there. Also notice all the rust on metal surfaces on a *Texas* truck that's never been off road and has under 20,000 miles.
Meanwhile, there was a three year old Tundra there with 120K on the clock, and the engine bay, while a bit dirty, still looked like new. What was that about "domestics having equal quality with the import names" again?
While I'm sure you're right about the quality (rust et al) under the hood, the Tundra, to the best of my knowledge, does not have the pulling power of an F-350. Nor does Toyota produce anything near the F-450, F-550 and so on.
When you're pulling 26K or better, the minimum you need is the F-350.
Notice the cut and taped wires with NO SEALANT OR COVERING OVER THE CUT ENDS!!! Do you know how to get out of the rain, are do you know when it's raining?
Most all vehicles that have a multiple engine platform, have a general wiring harness. That means there are wires that are not used if you have a different motor platform. If you look inside your computer you will find the same thing unused sockets and wire's .
