Hi All! New to the forum here, so thank you for answering my question. I apologize if this has already been asked. I attempted to look through the forums already to find a similar situation. I am planning on purchasing a used 2015 - 2017 Explorer this summer. Most of the Explorers I have seen do not have the factory tow package. I would like to get a popup camper as well to tow with the Explorer, so I am looking at a trailer weight of about 2,000 lbs before adding people and stuff for camping. If I add a class II or III hitch with wiring and install an additional transmission cooler, will that be enough to tow? I see that the additional tow a packages have an oil cooler as well. I would be driving in the summer, about 300 miles in Michigan. Is the oil cooler necessary or overkill? Thanks!
