Video Transcript for Review of Roadmaster Tow Bar Braking Systems Accessories - Second Vehicle Kit - RM-98450

Hey everyone. I'm Ellen here at etrailer.com and today we're taking a look at the second vehicle kit for your even brake Roadmaster system or your Roadmaster even brake system. That's going to be the supplemental braking system on your RV to help bring your towed vehicle to a stop. So maybe you've got a new towed vehicle or you want to add one to your fleet. This is going to allow you to do that without having to get an entirely new braking system. If you like the even brake, it's working well for you, you just want to add another car to work with it, this is the kit that you need.Now this kit specifically is for the even brake systems that are serial number 27497 and up.

So make sure that yours matches with that. Again, that's the number on the screen there. So this is going to be a kind of the newer model for that second vehicle kit. It does come with instructions that are specifically for installing the second vehicle, so it should make this a pretty simple install on that second vehicle for you. So we'll get our transmitter, a new breakaway switch, and umbilical to go between our towed vehicle and the RV.

Some hardware to mount the transmitter, also some wiring hardware, a new relay, and the wiring connection going between our breakaway switch and the transmitter. Again, it does come with instructions that are specific for just the second vehicle kit, so it makes it a little bit easier to get this installed. Should be pretty straight forward, it allows you to have that additional vehicle in your Armada, your fleet of vehicles to tow behind your RV. So that way you're able to save a little bit of money, a little bit of hassle, as far as getting that installed.So I hope this video has been helpful in deciding if this is going to be the right kit for you. If you need that kit, that's for the 27496 and below, we do have that kit here at etrailer.com.

That's going to be part number RM-98400, so you can find that right here at etrailer.com, along with all of the other accessories that you'll need for a safe and pleasant flat tow experience. So check out our other accessories right here at etrailer.com. Thanks for watching.

  • Roadmaster 2nd Vehicle Wiring on 2012 GMC Sierra
    For your 2012 GMC Sierra you can't completely connect the Roadmaster 2nd vehicle kit # RM-98450 or # RM-98400 to the trailer brake controller wiring under the dash . You can get the cold side of the brake light switch at that location which is the factory blue wire with white tracer. It is not recommended to get power or other functions from those wires.

  • Replacement Supplemental Braking System for Replacing Roadmaster RM-9400
    If you are missing the main assembly that sits in the floor board of the tow vehicle and applies the brakes you'd need to replace basically the entire kit since the second vehicle kit does not come with that. Since the RM-9400 was discontinued you'd be best served with the Blue Ox Patriot part # BRK2019 instead which is the best performing and easiest setup for this type of supplemental braking.
