For my application personally I will be towing a fairly small 4' x 8' trailer full of my stuff. At least 80 miles in each direction. So i'm def gonna end up going with the ECS OEM hitch with all the connectors. To each his/her own but the piece of mind of a tried and tested piece of OE equipment is worth the extra cash in my mind.
