Creating the immortal truck

I've heard a lot of people say this. Does anyone know why short trips are bad for vehicles?

I've heard a lot of back-and-forth on this subject. I also read the "Truth about Spark Plugs" thread. Has there been some sort of consensus reached on iridium plugs? Extending maintenance intervals, where possible, is my kink.

 

On short trips the vehicle (oil, fluids, exhaust) does not get hot enough to drive off water and volatiles, resulting in a build up of water and acids etc.

 

I can vouch for that. My work truck barely runs for 5 min going between buildings for maintanence and it had a new motor before 70,000 miles. It’s close to 90,000 now and the new motor already has a strong tick to it.

 

That's brutal. I'll keep it in mind.

 

Perhaps change out the secondary air pump filter. https://www.youtube.com/watch?v=Lh1c93zych4

Aside from drivetrain maintenance, I ceramic coated my truck to help prolong the life of the paint. Something to look into anyways to see if that's right for you.
I'd keep everything close to stock otherwise.

 

I had a peek through a few threads to get a handle on maintenance intervals. I have been led to believe that a lot of this has been pulled straight from Toyota's maintenance schedule. If you guys think any of this is kinda pointless or overkill, let me know. I'm not made of money and this is a good bit of stuff.

I also found this post, which I haven't compared against the recommended maintenance tasks:

 

I’m kinda surprised no one has mentioned the unifilter mod for the secondary breather.
