Howdy! Thanks in advance for any help. We have upgraded our tow vehicle to a 2017 expedition EL. We used to tow a pop-up trailer with a minivan and are now in the market for a bigger trailer. I'm unsure about the actual towing capacity of this vehicle based on looking at charts we can either tow 6,000+ or 9,000+. I've searched based on vin# and have specs on a trailer we are interested in. Can my expedition tow this trailer? Besides a weight distributing hitch, what other gear or mods to the vehicle are recommended?
