Every sunday evening at about 10-11pm I see a white 3g CTD quad cab long bed DRW with an ID # in the back wndow headin north on 65 south of Louisville. He is pulling the same trailer that is used for durabuility tests with the big windbreak, just no dead weight box? He has normal michigan tags and no extra gauges. Any idea if he is doin long term testing? And he is dead on the speedlimit. Any ideas?
