Trucks are certainly the most difficult to decode. But if you are using something like ChromeData for the VIN data, and combine that with the info from the dealer's site then you can usually narrow the vehicle down to a specific trim level.

Not always however. Dealers frequently have incorrect or missing information on their websites, so garbage-in, garbage out.

This is why scraping dealer websites for data is always going to be problematic. Far better to work with the providers to have them send you the data. It's faster, easier and you get far better data.

I used to work for a competitor in the same space as AutoRevo =) Chrome was ok, but there was another provider that had exact vin matches in their catalog. It was a bit more expensive, but made it so the trim field was a non-issue. I don't remember the name, it's been too long.

It might have been AutoData, but they have merged with Chrome. Edmunds has a decoder, but it's pretty laughable. I'm not aware of any other major players in that field outside of those.

Chrome offers 1-1 matches on VIN to style Ids for most OEM's, but it's an additional cost.
