This F150 I just got only has a 4 pin.
what heavy duty ultimate connector do you guys suggest?
thanks

7pin blade is the standard. you can wire/plug this in, or wire from scratch. http://www.etrailer.com/Wiring/Tow-Ready/30717.html
or this one will give you a 4f and a 7blade http://www.etrailer.com/Wiring/Hopkins/37185.html

the additional 3 wires on a 7blade is brakes,battery, and backup.

Second the multi tow above, whether you connect battery/brake/backup or not it gives you the ability to tow a trailer with a 7 pin which are becoming more common for RV trailers.

I have a 21' RV /camper so that's why I need the new connector.
is metal better or plastic.
