Can I Add A Wire Harness To My Camper To Make It Tow Another Utility Trailer

Published 10/20/2022

Question:

I have a 2005 Chevy Silverado truck with a factory bumper mounted 7 pin connector. I recently bought a 2019 northstar pop up slide in camper that has what appears to be a 7 pin plug powering the camper. I would plug it into the factory bumper connector to power up the camper. I recently bought a utility trailer to tow behind that has a 4 pin flat connector. What adapter can I use to plug in both the camper and utility trailer utilizing the factory bumper mounted 7 pin connector.

We highly recommend against double towing and many states either don't allow double towing or have numerous restrictions. There are some states that limit the total length of all 3 units, some only allow certain types of trailers behind the 5th wheel trailer, and some require a special endorsement on your license to be allowed to double/triple tow. I recommend checking the laws for any state you plan on double or triple towing in.

You will have to use a universal fit wiring 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 utility trailer has brakes it will be very hard to get power back to them to operate them.
