My DMax is a pretty truck but the beat to crap box, without bedliner, is under a tonneau cover so you can’t see it. Another thing you can do is check the receiver hitch, if it’s scratched / rusty inside then you know its being used to tow something. 🙂
Plenty of 'em out there homie. I bought a used DMax in 2019 and despite being a Denali edition it didn’t come with a bedliner, just a rubber mat for the floor. I should have had one sprayed in when I got the truck because my box is now beat to shit.
I think all the previous owner did with it was tow a horse trailer.
