When you are changing out for the 7-way connector setup it is probably a good idea to get the 4-way 7-way combo connector. There are many times I need to use my 4-way setup here with my utility trailer etc...
My F150 setup has this dual connector with the 4-way pin setup on one side and the 7-way BLADE setup on the other side...
I also carry one of these tester adapters that plugs into the truck side for the RV 7-way and trailer 4-way plugs. Most useful items to determine if the problem is on the truck side or the trailer side when you are having trailer lights problems
Note the utility trailers use the round pin connections where the RV trailers use the flat blade type connections.
ADDED NOTE: I just noticed the RV PLUG photo shown is not for the RV TRAILER should look like this... Hopefully you get the idea hehe...
ETRAILER.COM has everything you need for this change out... ETRAILER also has videos for installing most of their products which is very helpful...
Of course you really need to nail down the trailer weight and towing capacity of your truck. No need to change out all of off this if it turns out your truck is not capable of towing the trailer "SAFELY". Note I did say "SAFELY"...
Also since you new to all of this towing etc please read up on the DOT REQUIREMENTS of having working ELECTRIC BRAKEs when on the roads as well as a working TRAILER EMERGENCY DISCONNECT feature that will lock up your trailer brakes in the event the trailer becomes disconnected from your truck when being towed. This is a "LAW" if your trailer is equipped with electric brakes.... For the RV Trailer this also means you must have a working battery installed on the RV trailer as well when being towed.
Just some of my thoughts
