Roadmaster tow bar adapter for 1" D-tab bumpers — Steel forged, powder‑coated pair, fits motorhome-mounted tow bars

Roadmaster 035-1 is a forged steel adapter that lets you pin a Roadmaster motorhome-mounted tow bar directly to bumpers with 1" thick D-tabs, providing a durable, easy-to-install alternative to baseplate setups.

Not every bumper or tow setup requires a permanent baseplate. The Roadmaster 035-1 adapter replaces the ends of compatible Roadmaster tow bar arms so you can connect to existing bumper shackles or D-rings. Built from drop-forged steel and finished in a protective powder coat, these adapters are manufactured in the USA and intended for use only with Roadmaster motorhome-mounted tow bars—not Stowmaster or Tracker models. Before towing, verify the bumper manufacturer permits flat towing with their bumper.

How does the 035-1 adapter attach to my tow bar and bumper?

The 035-1 is designed to replace the terminal ends of Roadmaster motorhome-mounted tow bar arms so the tow bar pins directly into your bumper’s D-tab/shackle. Installation is straightforward when you follow the supplied instructions and hardware. No welding or permanent bumper modification is required.

• Drops into place replacing original tow bar arm ends
• Secures with provided pins and retaining hardware
• Fits bumpers with a 1" thick D-tab
• Requires verification that bumper manufacturer allows flat towing

What materials and finish are used, and why does that matter?

The adapter is manufactured from heavy-duty drop-forged steel for strength under towing loads, then coated in a durable powder finish to resist corrosion and abrasion. Those choices improve longevity and keep moving parts operating reliably over time. The powder coat also helps maintain appearance in road conditions that can accelerate wear.

• Drop-forged steel core for toughness and load-bearing capacity
• Protective powder coat resists rust and chips
• Precision manufacturing at Roadmaster’s U.S. plant ensures consistent tolerances

Will these adapters work with my vehicle and tow bar model?

The 035-1 fits bumpers equipped with 1" thick D-tabs and is compatible only with Roadmaster motorhome-mounted tow bars. It will not fit Stowmaster or Tracker tow bars. Always confirm both bumper and tow bar compatibility before purchase.

• Designed for 1" thick D-tab shackles
• Compatible exclusively with Roadmaster motorhome-mounted tow bars
• Not suitable for Stowmaster or Tracker tow bars
• Check bumper manufacturer’s towing approval first

How simple is installation and what hardware is included?

Roadmaster packages the adapter with the necessary hardware and step-by-step instructions to swap in the adapter ends on your existing tow bar arms. Typical installation requires basic hand tools and low mechanical experience. If you prefer, professional installation at a shop is also an option.

• Includes pins, retaining hardware, and instructions
• Replaces only the tow bar arm ends—no bumper drilling required
• Most installs complete with common hand tools
• Professional installation available if you want expert fitment

Who is this for: The Roadmaster 035-1 is aimed at owners of Jeeps, trucks, and SUVs that already have robust aftermarket or factory bumpers with 1" D-tabs and who use a Roadmaster motorhome-mounted tow bar. It’s ideal for drivers who prefer a removable, non-permanent connection to their bumper shackles instead of installing a baseplate, and for anyone who values American-made fabrication and durable construction. Confirm that your bumper manufacturer approves flat towing and ensure you’re using a compatible Roadmaster tow bar before purchase.
