Is it a fleet truck? Looks kinda like it.
That could be good or bad, most fleet trucks get the service that they need but can be driven by (relatively) uncaring employees.
Crew cab is always nice.
What I can see of the interior looks decent, maybe the steering wheel leather starting to go bad (high mileage, skin oils, etc). Mine had just over 400 K on it and my leather wheel was breaking down the same way.
The EGT and boost guages could be good or bad, hard to tell. On the good side, someone knew enough to install them so hopefully they watched them. Or it could mean the truck has spent a long time towing.
The fifth wheel foot, high kms and DOT number could very well mean "hotshotter truck", but I could be wrong there.
466,000 is kinda high, even for a dmax. That's what would make me look real close and maybe even shy away from it.
How much are they giving you for payout on your 6.5?
