I can understand your frustration. I will try to take a look at each. It might help to post on each page what features make it them a certain trim. Unfortunately, we have a lot of posters who BS us or just outright guess on models, years and trim levels, so sometimes we don't always trust that the IDs are correct. That is why sometimes info is blanked out.

As for the Econoline, they were sold as both Econoline and E-### depending on the year. And we find a lot of them are older vans given the newer front ends by production companies, so the natural reaction is to blank them out if they are left without a year or if they look incorrect until somebody who knows them better can give their opinion.
