Question:

Hi I have a seven blade socket on the rear of my 2014 Tiffin Allegro Bus. Does this merely plug into that socket and then it gives me 7 blade and 4 flat access at the same time? I use magnet mounted lights on my tow vehicle I need the 4 flat socket for. I use a 7 bade to 4 flat adapter now. However, Id like to add your Roadmaster tow vehicle charging kit. What will I need to purchase to connect the 7 blade RV socket so I can install your Roadmaster battery charging kit? Thats assuming this adapter will give me access to 7 blade and then 4 flat for the lights. Thanks

Hi Scott,

The Curt Replacement OEM USCAR Trailer Connector # C42JR does not support both the 4-way and 7-way at the same time so you would need to switch to the Hopkins # 30955 if you have a USCAR style connector or the Hopkins # HM48470 if you don't. Either would allow you to plug in your 4-pole lighting as well as a 7 to 6-way cable # RM-146-7 so that you can run a charge line # RM-156-25 to the towed vehicle. If there isn't a charge line ran to the motorhome 7-way then you can also pick up the # RM-156-75.
