Know a few people with 5.7 engines in Tundras and Sequoias, which is the same vehicle but an SUV. Never heard a problem with reliability. Likewise my mechanic says its a great truck...on the rare occasion it needs to be worked on.


The 4.7 is from the UZ family, while the 4.6 and 5.7 are from the updated UR family. Completely different including block.

The 5.7 UR has had way more issues, and early failure than the previous, including cracked blocks, and piston failures. Camshaft tower leaks are very common on these, with some having the issue before 10k miles. But yet they are still using the same sealant. This leak is hard to find, and many donít know because it starts out very slow.
Yes, they can be reliable, but not always.

Typical aluminum that is not touching any other metal oxidizes very slowly. The metal that Ford uses is a unique alloy that has a unique coating (Alcoa patented) applied while the sheet metal is coiled. All of this reduces oxidation.

Ford completely redesigned their stamping process, cleaning, priming and painting process to maximize the life of these body parts.

Are they perfect ? No. But they will out last steel in winter salt conditions by many, MANY years. Lets compare notes in another 10 years.

Aluminum works well with the Airstream because I believe the shells of those trailers last 50 plus years.

There are probably alot of 1970 Airstream trailers where the shell is still good

back to the Tundra I just went one a 250 mile trip to pick up a car. as leaving town I got behind a T/T, an Airstream looked all of 28'. I followed this for 70 miles on a curvy two lane highway at speeds 60-70mph. the wife and I commented on how wide the Airstream looked and how smoothly it was towing, like an arrow. even when large truck would pass. I couldn't see what was towing it enough to determine what it was. they did have their hitch set up good as the truck and trailer were setting just about dead level. we finally got to the freeway and I followed for a few more miles at just short of 70mph. they would hit dips in the highway and it would porpoise a little but nothing abnormal. I finally pulled out and passed them, and LOW AND BEHOLD IT WAS A CREW CAB TOYOTA TUNDRA TOWING IT. i'm not a Tundra fan so just my 2 cents.

What Truck is Best Long Term?

New Tundra is coming out a little more than 1.5 years from now as a 2022. It will have a 3.5 liter turbo V6. No more lumpy V8.

I love my F350 6.7L - used to drive a tundra and never going back.

Alot of those airstream guys use Propride or Hensley hitches , the cost of those TTs what's a 3k for a WDH.
