2013 Ford Explorer Limited 4dr SUV AWD (3.5L 6cyl 6A)
I just bought a 2013 Explorer with a tow package with the intent of occasionally needing to rent a trailer as I had done with my previous vehicle (a 2009 Edge).
I found out after the purchase that U-Haul has black-listed all model years of Explorer and will not rent towable equipment that will towed by any Explorer.
This fact was not know by the dealer.
U-Haul has black listed Ford Explorers for years.
It was based on the previous models tendency to roll over while towing trailers at high speeds.
It is a shame they didn't upgrade that stance with the new model Explorers.
One reason I did not opt for the tow package for mine.
Sorry you didn't find out until after the fact.
After seeing this initial post I did some more information digging. Most of the information I was finding was old so I decided to contact Uhaul directly through thier instant chat. The tech, Kimberly, stated that they have blacklisted most of the Explorers but the newer ones are cleared now. I specifically asked about a 2013. Kimberly did however state that Uhaul recommends that you get a recent inspection to ensure that everything is good to go. I hope this helps other current and future Explorer owners.
