Today we're going to be taking a look at the Roadmaster Extension Loop for towed vehicles. This wiring loop lets you connect your RV to your towed vehicle. It's going to feature the dual trailer male-end plugs that would simply plug into a four-way flat vehicle end connector. This loop has a measurement length of 6 feet long, and each connector is going to come with a dust cap. That's going to do it for today's look at the Roadmaster Extension Loop for towed vehicles.
Crazy expensive for 6’ of wire. Unbelievably, no one else sells the same piece of wire?!??!
I had installed the ROADMASTER tail light wiring kit on my towed Jeep which included this jumper cable to connect the car to my RV. Somehow it dragged on the ground while towing and wore through some insulation and one wire. I was very glad to see I could order just this jumper cable to make my install as good as new. ROADMASTER helped me identify the part number and etrailer stocked them at a good price.

Its been a year, and everything is still working great. I am more careful how I support this jumper now.
Hard to find item and at a great price point! I use it to connect my 90 Suzuki to my 2009 Explorer when I tow it to the beach!
My review is based primarily on the service I received when calling etrailer.com. I cannot brag enough on how friendly, helpful, and efficient the representative was on the phone. I needed to purchase this product as a replacement for a component which came in a larger package/bundle I had previously purchased. I described the individual item I needed, and she directed me right to it and completed my order then and there, saving me the much larger sum of money which would have been required to purchase the entire package all over again. It was so easy. I'm very impressed with not only the inventory and products, but perhaps even more so the staff and service of this great company. I highly recommend them.
We ordered tow mounts, road master tow bar and some accessories from etrailer for a 2009 Suburban. All the items arrived within a few days and packed in secure boxes. After just a little drilling the mounts went right on, the instructions are very detailed and easy to follow. I highly recommend etrailer.com for your towing needs.
Needed make to make extension for trailer lights. Which is not easy to find. Thanks to etrailer.com, I got what I needed. Easy to order on site. Delivered in a timely manner. No complaints from here!
Easy to install and needed for extending the wiring for the tow hitch.
First time buying a tow bar. Great experience with Jesse at errailer. etrailer videos are excellent.
Purchased this as a backup for the one I purchased earlier. The one that was replaced had gotten nicked when folding or tow bar.
Product was just as described and met my needs perfectly. Needed a replacement quickly for a planned trip and item came on time as promised.
Nice and small, bunches better than the coiled cable I had before.
Exactly what I needed for towing my Jeep. Arrived quickly. The pigtail currently on there was too short.
Perfect! Hard to find this cable in local stores and etrailer not only had it, but at a great price.
Chelsea was an amazing product specialist! Knowledgeable and professional.
Checked with several RV shops, marine stores, and a place that sells trailers. The trailer placed rigged up a cable for $30. Spent more than a few hours scouring the web till I found etrailer.com and not sure of the nomenclature of what I needed, emailed their customer service with a description of the application and sent a picture of the connectors and within a couple days was sent the pic of this product. I was apprehensive at first until I viewed all the pictures then I was sold and immediately placed my order. Received the product 2 days ahead of the predicted arrival date and couldn't be happier. Highly recommend etrailer.com. I have actually bookmarked the site for later reference.

Keeps on working as expected-still the most expensive piece of wire I’ve ever bought for its size and makeup. I’ll be building my own of this ever gives up!
