Can I tell if it has the factory tow package based off VIN?
Capt, try an online service called CompNine (www.compnine.com). If your VIN is available in their database, the four-page report will provide a code and associated description of every option that was installed on your vehicle when it left the assembly line. There is a disclaimer on their webpage that says they only have VIN data for Fords up to 2012, but I was able to insert my 2013’s VIN and it worked fine. Anyway, you can enter your VIN at their homepage to see first if they have a report for your Expy; if they do, it costs $5 for five VIN checks. It’s legit – it worked for me last Oct, and answered/confirmed a lot of option questions before I purchased the vehicle. Worth the five bucks.
The report I purchased for my VIN showed that my Expy came with the heavy duty trailer towing pkg, trailer sway control, and a heavy duty aux trans oil cooler.
Associated point: If the vehicle still has a window sticker, all the info you're looking for will be there too.
