Love the rvi4 brake. But nowhere was it mentioned that you needed to buy two additional items to make the display work completely. Battery charger and breakaway modules. I feel that they should have been part of the boxed kit. Especially for the money. I ended up buying the battery charger but I’ll watch my camera for a breakaway for now.

The Curt Towed Battery Charger (part #RVI74FR) is one of those small add-ons that makes a big difference when you’re flat towing. A lot of supplemental braking systems draw power from your toad’s battery, and without a charger you can end up at camp with a dead vehicle that won’t start. This kit keeps your battery topped off the whole time you’re towing by pulling just the right amount of power from your motorhome and feeding it back into the towed car. It’s designed to work seamlessly with RVi brake systems like the Shadow 2 and RVi4, so everything stays in sync without you having to think about it. The setup is simple, it’s lightweight, and it gives you peace of mind knowing your vehicle will be ready to drive as soon as you unhook. For RVers who do long hauls or run accessories in their toad, this charger is a must-have for hassle-free trips.

  • Installation of Curt RVi Series Towed Battery Charger+ in 2025 Ford Ranger Raptor
    Hey Doug! The Curt RVi Series Towed Battery Charger+ (TBC+) for Flat Towing # RVI74FR actually installs on the vehicle side so it will go in your 2025 Ranger Raptor. Your Jayco probably has a charge line already, which would be a 12V line running through your 7-way. If you don't have one you can add one using the Roadmaster Battery Charge Line Kit for Motorhomes # RM-156-75. The installation of the TBC+ is pretty simple so you can probably do it yourself. You have to mount the box and...

    Hey Brian, congratulations on the new Wrangler! I would be happy to help you out with this.

  • What Is Advantage Of Curt RVi Towed Battery Charger # RVI74FR Over Standard Hot Lead?
    Hello Alan, thanks for reaching out. The main advantage of using the Curt RVi Towed Battery Charger # RVI74FR instead of running a simple hot lead is that it properly manages and protects the charging circuit between the motorhome and your Gladiator. The RVi charger regulates voltage and current, which helps prevent overcharging, backfeeding, or electrical issues that can occur with a direct charge line, especially on newer vehicles with sensitive electronics. The unit also has built-in...

  • Can a Battery Disconnect be Installed on the Positive and Negative 2020 Buick Encore GX Terminals?
    Hey Darrell, thanks for reaching out! The Roadmaster Battery Disconnect # RM-766 is only designed to be installed on the positive terminal (since the activation button pulls power from the positive terminal), so I recommend using the Roadmaster Battery Charge Line Kit # RM-156-25 as opposed to the RVi # RVI74FR for keeping your 2020 Buick Encore GX battery topped off. You won't need the extra charging power of the RVi kit unless you are planning to have quite a few things pulling power...

  • Can 2017 Toyota Tacoma TRD Be Flat Towed
    Hey John! The answer in this case is yes and no. Officially, you cannot flat tow your 2017 Toyota Tacoma TRD. If you look in the owner's manual it states "Your vehicle is not designed to be dinghy towed (with 4 wheels on the ground) behind a motor home." However, base plate kits exist for the Tacoma which means enough people do it anyway. If you want to flat tow the vehicle and it is a manual you can put it in neutral, put the transfer case in 2WD, and accept the risks. For an automatic...

    Thanks for your question, Dale! The Brake Buddy Classic 3 part # HM39494 will pull power from your Xterra's battery. You will also want to pick up the charge line kit part # RM-156-25 so that you can keep the battery charged when flat towing. We also have the Curt RVi Series towed battery charger part # RVI74FR. What's really cool about this one is that based off the color of the LEDs it will tell you the health or status of your vehicle battery. Let me know what you think or if you...

  • Parts Needed to Flat Tow 1974 Volkswagen Beetle With Ready Brute Tow Bar
    Hi David; I can provide you with the parts you need to set up your 1974 VW Beetle for flat towing. However, it will be up to you to find an adapter so the Ready Brute can connect to the base plate kit (Roadmaster is the only one available). From what I have heard if you call NSA they will be able to make a custom adapter for you but I would verify this information before purchasing the rest of the parts. I would also ask them if they have run into any issues with their tow bar on a Roadmaster...

  • Does the Curt RVi Series Towed Battery Charger+ Provide Backflow Protection?
    Hey Fred, welcome back. The Curt RVi Series Towed Battery Charger+ for Flat Towing item # RVI74FR does indeed provide backflow protection. You won't have to worry about damaging your motorhome when using this on your 2020 Ford F-150. Adding the Roadmaster Single Park Light Diode item # RM-690 to the Curt item # RVI74FR would be redundant. If you have any additional questions, go ahead and click on the box that says Reply to Jerred H and I'll be happy to answer them.
