Looking for advice on inspection of a pre used truck before buying

I am going to look At a cascadia 2013 dd13 18 SPF 455 hp 3.55 ratio 380000 miles on it ,listed for CAD $ 79500 /USD $59500 which I am interested in buying . As it is in a different city than mine so I can't take my mechanic with me to have an expert look at , so I wld like some advice/opinions what are most definite things I should be looking at on the truck besides I am getting oil analysis . It's a trade in at a Volvo dealership n I know what company it had ran for earlier even though dealership cAnt provide maintenance reports on . So what should be the other test n reports I can pull to make sure everything is fine n dandy with the truck. Your advice/opinion will be greatly appreciated. Thanks

 

Thanks for your reply ... I was wondering if they would be able to pull a report on a truck that's in Canada as well. Cause I am a canadian. And if yes what do they all need to pull that report.thanks

 

I asked him cuz of his busy schedule he can't make time to get on a 400 mile road trip with me but yeah I will definitely ask him if he knows any mechanic in area . Thanks

 

What kind of engine issue dyno would highlight .. And you think any diesel repair shop would have a dynamometre or there's only specific places that offers dyno service
