When you’re logging long miles behind the RV, you want gear that feels rock solid. This base plate kit uses computer-cut, all-steel construction for exceptional strength and a black powder coat finish that resists corrosion. It bolts directly to the frame to create fixed attachment points that stay put, giving you a strong and stable connection through every mile.
The fixed arms on this setup mean there’s nothing to misplace or reassemble when it’s time to connect your tow bar. Hooking up is direct and reliable, and if you’re using a Roadmaster tow bar with a crossbar (910021-00, sold separately), the included mounting hardware and instructions make the process clear. Everything stays aligned so you can spend less time fiddling and more time rolling.
Already have a Blue Ox Aventa or Avail tow bar? You can make it work with this base plate by adding the Roadmaster Base Plate to Blue Ox and Tow Bar Adapter # RM-033. The adapter bridges the two systems cleanly, letting you keep the tow bar you trust while running this Roadmaster base plate kit. It’s a practical way to reuse your existing setup without starting from scratch.
No hunting for extra bolts or guessing how it all fits together—the kit includes complete mounting hardware and detailed instructions. Everything you need to bolt it up comes in one package, making it easier to get your towing system built right from the start.
The black powder coat finish does more than look clean—it protects against rust and chips from road debris over time. Combined with the steel frame brackets, it’s a setup designed to handle years of towing duty while staying reliable and secure mile after mile.

It’s been great. I only use it to tow my huntn’ rig and never a problem. I’m 87 now and can load and unload by myself.

Install completed and many miles of care free towing behind our motorhome. Fixes suggested made for a simple install. Should be incorporated in future kits. I wont charge for the redesign. :+~ I spent my working life as a mechanical designer builder for a major industrial equipment company.

I spoke to my contact at Roadmaster and he said, as this kit is for vehicles 30 plus years old, it does not fit the new systems, verbiage, and formats that are currently used in installations. With this vehicle being an uncommonly flat towed vehicle as well, they are limited to the one vehicle that came into their shop, which was being the model to design the installation instructions. This can lead to little things not being detailed in the instructions.
