Opinions on low mileage older Japanese trucks?

I have started the hunt for a 25,950 GVWR cabover to replace our 19,500 GVWR Isuzu NRR. A GMC T-7500 or the Isuzu or Mitsu equivalent.

I want to stick with pre 2008 (which isn't too hard since they seem to have stopped importing them to the USA after 2008). Occasionally I notice a very low mileage vehicle, like a 2006 with 4,400 miles. These usually have a fairly high price tag commiserate with the low mileage.

What is your opinion of this? On the one hand, low mileage like that probably means not too much abuse could have been done to the frame/steering components, but I wonder how the vehicle was serviced if it was only used for 4,400 miles over 8 years. Did they only change the oil and fuel filters once every 4 years? Did the engine sit idle for 3 years?

I am cautious to pay a premium price for a 6 cylinder Isuzu or Duramax engine only to find it needs 6 new injectors and a fuel pump because it sat unused. Is this a unreasonable worry for ultra low mileage vehicles?
  • low miles doesn,t mean LOW ENGINE HOURS, our guys NEVER turn the motor off and the trucks have very few miles on them.
  • You need to be aware of scammers selling high mileage trucks. They remove the interior and dash cluster from a new truck and then run the hell out of it. When they're ready to sell it, they put the original interior and dash cluster back in and sell them as low mileage trucks.
  • I don't think that is so unusual. Commercial vehicles may be used from building 2 building on an industrial campus.
    We have a box truck at the office that goes back/forth between building and rarely sees the open road.

    As long as it has been serviced, I would not hesitate.

    Many diesel trucks have hour meters in addition to odometers...you can check for hours of service...which may be more important then miles.
  • 4,000 miles over 8 years on a commercial truck?

    Unless they have a darn good explaination and I have a mechanic go over it with a fine tooth comb and give the OK, I'm running.

    Even if it wasn't abused:
    - I would expect seals and rubber parts to be dried out.
    - What are the odds the engine was regularly gotten up to full operating temperature?
    - What was the oil change and maintenance regime?
    - What's had time to grow in the fuel tank, clog the injectors, etc...?
