Hello, We are new owners of a 2013 Nissan NV 3500 HD SL trim (leather, navigation, tow). We are looking to pull a travel trailer that weighs 6000 pounds, loaded with our gear probably 7500. From everything that I can figure out, our van is capable of towing 8700 since it has the Nissan factory towing package? Can anyone confirm that this is correct? I know we have to have the electronic brake control installed first. Has anyone pulled a load of similar weight? Could you offer me any insight? Thanks in advance!
