Video Transcript for Review of Roadmaster 7 Way To 4 Way Coiled Tow Bar Power Cord - RM78BQ

Hi, everybody. Andy here with etrailer. Let's take a quick look at this Roadmaster seven-way to four-way coiled tow bar power cord. Now this is going to make flat towing simpler and more hassle-free. This connects to your RV's seven-way plug, and the other end will connect to your vehicle's four-way plug. So all of your signal lights, such as your brake lights, turn signals, and running lights are going to stay synced up and working properly.

That way, drivers behind you can clearly see what you're doing on the road. And this is designed specifically for flat towing. So it's gonna help you hook everything up quickly and cleanly without having to mess with complicated wiring. Now if your RV and your towed vehicle use different type of connectors, this is going to act as the bridge between them, letting you keep using equipment that you already have instead of replacing it. The coiled cable design is another nice touch.

This is going to keep the cord from dragging on the ground or getting tangled up while you're traveling. It stretches when you need it to and then it contracts when you don't, which is gonna keep things neat and safer on the road. And since this is built to work with Roadmaster systems, you can count on a solid, reliable connection if you're already using their towing components. But overall, it's gonna be a straightforward solution that's gonna keep your lighting system working properly, and it's gonna make the whole flat towing setup easier and cleaner. If you have any other questions, don't hesitate to reach out.

We do wanna make sure that you're getting exactly what you need. Well, again, my name's Andy. Thank you for joining me.
