John, I agree.
I did look online a few months ago to find and was successful with finding a database of all the C4C vehicles. Fortunately the rules for the game didn't really permit any large vehicles like that, so no Excursions were involved, and I just did a search, and no F-350 of any year was involved.
There are a number of 250's. In that year range I counted six just from going through the first 11,500. However, each one had a 5.0 or 5.8L gas, none were the 7.3.
Oh yeah, and I thought my database was big...
