Buying budget/used TV with high mileage...

...how much is too much?

I'd like to 'upsize' from our current '06 Sierra 1500 5.3l to something in the 3/4-1 ton range for towing our TT, with an eye towards getting a larger TT down the road a bit, or a small-to-medium 5'er. Have to have more truck before we can start looking for a bigger trailer, so...

For a variety of reasons, a new, or even late model truck ain't in the cards. Period.

When I start looking around in our price range... pretty much everything has 100-200k miles on it. Sometimes more.

Traditionally, I've usually taken the approach that if someone is racking up 30-40k miles per year on a rig, it's likely *all* highway, and probably very little of it towing. Granted there is not really any way to *know* that, unless you are literally buying from your neighbor or friend... but does that sound like a reasonable assumption?

Talking primarily diesel here, and largely (but not exclusively) Ford. 6.0l with 100-150k vs. 6.4l with 150-200k or 6.7l with 200K+

On the one hand, our use would be fairly light... probably <5k miles per year, *maybe* 7k in an exceptional year. On the other hand, we are in the western states (WA/OR/ID/MT) so... mountain passes are the norm, not the exception.

Yes, I know it's not ideal. But its the hand I'm currently dealt.

  • So... no validity to the notion that if a 6.0l Powerstroke was going to eat itself, it would probably have done so by now? What if it's already been 'bulletproofed'?

    $10k for a fuel pump replacement?!? How does that work?
  • X2. Skip the 6.0 and 6.4L diesels. The 6.0 can be made good with lots of work, but it would have to be almost free, for all the extra work to cost less than simply not buying that diesel. I'd avoid any 6.4L over 100k miles. It's a fuel guzzler, and while it has far fewer problems than the 6.0, it has some very serious fatal flaws. The 6.7L is by far a much more reliable overall package, but if the fuel pump goes, that's a $10k+ repair.

    For 5,000 miles a year, I'd look for a V10. You can pick up a reliable one for less than a 6.7L fuel pump job....
  • I want my TV dependable. I can get around, explore etc. without a new TT/5er while its repaired etc., but not without a good TV.
  • 2 of your 3 choices mentioned are 2 of the 3 worst diesels of the last 20 years, IMO. That’s probably why they seem more affordable based on miles vs other brands.
    If a guy was saavy, a 6.0 or 6.4 can be a great budget rig, but not for the mechanically uninclined.
    And yes it’s as important to read the owner as it is to inspect the vehicle, IMO, when buying used, especially well used. Also, I generally prefer a vehicle that has had valid parts replaced at expected service life intervals over the one that “has never had a problem, never needed anything”. IMO those are the ones that are going to nickel and dime you more.
