Question:
Hi Looking to improve the 7 Way connection between my 5th wheel and 2021 GMC with the bed mounted connector. Someone pointed me to the EZ Connector. Is that the best option and if so which of their products is best fit considering the bed mount connector. Thanks

Hello Peter, thanks for reaching out. The EZ Connector is definitely a good option for upgrading the 7-way on your 2021 GMC. They provide a much more secure/watertight connection than standard 7-ways. If you want to do the plug in the bed, what you will need is part # 319-S7-09. Then you can either use the Trailer Connector Adapter # 319-R7-52, or you can replace the 7-way on your trailer with part # 319-S7-10.
