I can't trust any of the templates. Had experience with all of them being slightly off when putting against true life measurements. So...sure for proofing purposes you could use them, but why do the work twice and pay the extra money for them? If you get your hands on their actual vehicle or even a photo of it from each angle...no only can you verify measurements etc..but also see any other issues like dings, un-wrapable accessories or panels, etc. The customer won't usually think to mention the bumpers or wheel wells are plastic etc. Even the difference between 2 years might mean a lot of odd curves or recesses on the side or tailgate, makes a difference in install and design.
