Can You Add A Wire Harness To A Travel Trailer To Make It Tow Another Trailer.

Question:
Hello, Is there a Curt wire harness that will fit a travel trailer at the rear for towing doubles. I have a Keystone 2014 Cougar and I am installing a RV hitch.

You will have to use a universal fit wire harness like the Universal Wiring Harness w/ ModuLite and Brake Controller Harness - 7-Way Trailer Connector # 22551. This will only work if both trailers have LED lights.
Also if your second trailer has electric brakes its going to be very hard to get power back to them to operate them.
I also recommend checking local laws and regulations about towing doubles and making sure it is safe and accepted in the areas you will be in.
The more length you add to a tow situation the more unsafe it can become.
