Going to be buying a trailer for the Mustang in a month or so. Seeing pretty good deals on a new 16' steel open deck with drop in back (which is nice for header clearance getting on and off). Nice and light, only 1440 lbs, rated for 5000. Towing with a 4.6 F150 auto so want to keep the weight down. So is a 16 footer OK for our cars?
