Recommendations for a 7-Way to 4-Way Coiled Extension to Flat Tow a Jeep Liberty Behind a Motor Home

Question

Question:

I dont think that this product will stretch long enough to connect my rv 7 way to my jeep liberty 4 flat tow bar wiring kit with my roadmaster falcon tow bar extended . Can I get coiled wire in a longer length.

The Hopkins Heavy-Duty, Coiled Trailer Connector Adapter, # HM47075, measures 3 feet long when stretched. This will most likely not be long enough for most flat towing applications unless the 4-Way end on the vehicle has some slack that you can pull out.

You could just add a 4-pole loop, # 18045, which will provide another 60 inches of length. There is also a 48 inch loop, # 18044. A longer coiled cable is not available unless you use # RM-1064-B (8 feet long) and then wire in 4-Way flats using # 48195.

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…
