What specific pre-purchase inspection points for a 2018 F-150 should I request?

[Dennis.T]

I'm seriously considering buying a used 2018 Ford F-150 from a private seller, and it looks clean in the photos with decent service records. The seller is agreeable to an inspection, but I'm not sure what exactly I should be asking a mechanic to focus on for this specific model and year, beyond the general checks. For those who've bought used trucks, what are the key problem areas or common issues a pre-purchase inspection should absolutely cover for a vehicle like this to avoid expensive surprises down the road?
