yes, calling it a '1.5T' or a '2T' is meaningless, what they'll want is the GVW, which could vary depending on wheel/tire equipment and springing, the trucks are pretty much identical otherwise - if the vehicle doesn't have the tag on it, then go by the manual - or get the info kit for your year and print out the relevant pages for the authorities
