A-Frames: Supplied & Installed
NEW Roadmaster Towmaster 2 with InvisiBrake
A complete flat-tow solution — A-frame strength and automatic braking in one package.
The Roadmaster Towmaster 2 with InvisiBrake is our most capable flat-tow package. The Towmaster 2 A-frame delivers fast, single-person attachment with exceptional rigidity, rated to 3,750 lbs (1,700 kg) and built to a 1.2 metre length to prevent jackknifing. Paired with it as standard is the InvisiBrake electronic vacuum servo assisted braking controller — a fully hidden, automatic system that applies your towed vehicle’s brakes every time you brake the motorhome, with nothing to connect or remember each trip. Together they provide everything needed for safe, legal and effortless flat towing.
Roadmaster is a family-owned American manufacturer, founded in 1970, and the Towmaster 2 is its highest-quality, longest-lasting A-frame.
Roadmaster Towmaster 2
EZ Lock Coupling
Quick, strong attachment with a clear visual and tactile confirm. Anti-binding release levers allow effortless disconnection even under load.
Autolok Easy Hitch
Automatic alignment centres the towed vehicle as you reverse — straightforward single-person coupling every time, no assistant needed.
Folds Away When Not in Use
The A-frame folds neatly against the towed vehicle when not in use, keeping things tidy and out of the way on site or at home.
Built to Last
Solid stainless steel drawbars, improved lynch pins and a baked-on powder-coat finish. Computer engineered (FEA) and real-world destruction tested for confidence across years of use.
Roadmaster InvisiBrake
Truly Set-and-Forget Braking
Once installed there is nothing to connect, activate or remove. InvisiBrake works automatically via your existing electrical harness every single trip.
Power Brake Support
Energises your towed vehicle’s power brakes so it stops as if being driven — not on a flat, unpowered pedal like many rival systems.
Battery Charging Included
Keeps your towed vehicle’s battery topped up while towing — arrive at your destination with a healthy battery every time.
Safety as Standard
Breakaway switch activates the towed vehicle’s brakes on separation. Two-stage in-motorhome monitor provides visual and audible brake confirmation. NCAP safety features retained.

Blue Ox Acclaim Tow Bar BX4330 (Ball Coupler)
An adjustable, rigid A Frame with electronic vacuum servo assisted braking system, providing the progressive braking. Adapted for the UK Market with a 50mm hitch.
