Introduction: What Is an A-Frame?
An A-frame towing system (often just called an A-frame) allows you to tow a small car behind a motorhome using a triangular frame that connects the tow vehicle to the motorhome. For many motorhome owners, it can be a practical alternative to towing on a trailer or using a dolly.
But buying the right A-frame is not as simple as choosing the cheapest model online.
There are legal considerations, braking requirements, weight limits, compatibility concerns, installation costs, and major differences in quality.
This guide covers everything you need to know before buying.
Chapter 1: Why People Use A-Frames
The Benefits
Convenience
- Take a small car with you while touring.
- Easier than moving a large motorhome for every local trip.
- Faster setup compared with trailers.
Lower Costs Than Trailers
An A-frame setup can often cost less than a full car trailer and avoids:
- Trailer storage issues
- Extra tyres and maintenance
- Trailer insurance in some cases
- Additional weight of a trailer
Easier to Store
Unlike trailers, A-frames take up minimal storage space.
Common Uses
A-frames are popular with:
- Motorhome owners
- Full-time tourers
- Caravan users
- Seasonal travellers
- European touring enthusiasts
Chapter 2: Is an A-Frame Legal?
The Big Question
This is usually the first question buyers ask.
UK Considerations
In the UK, legality often depends on:
Braking Compliance
The towed car usually needs:
- A compliant braking system
- Overrun or assisted braking system
- Breakaway safety system
Lighting Requirements
Your towed vehicle generally needs:
- Indicators
- Brake lights
- Tail lights
- Number plate visibility
Weight Rules
You must consider:
- Motorhome towing capacity
- Gross Train Weight (GTW)
- Towed vehicle weight
- Nose weight limits
European Travel
Rules may vary from country to country. Some travellers prefer trailers for mainland Europe due to differing interpretations.
Always verify current regulations before travelling.
Chapter 3: Types of A-Frames
1. Basic Unbraked A-Frames
Usually for very light applications.
Pros

- Better for heavier cars
Cons
- More expensive
- More complex installation
3. Self-Centering A-Frames
Designed for easier towing geometry and smoother tracking.
Benefits
- Better handling
- Easier hookup
- Reduced stress on components
Chapter 4: How Much Does an A-Frame Cost?

- Standard installation
- Basic braking setup
Mid-Range
£2,500–£4,000
Often includes:
- Better engineering

Extra Costs To Budget For
Do not forget:
- Installation
- Wiring kits
- Brake integration
- Vehicle modifications
- Annual servicing
- Replacement parts
Chapter 5: Choosing the Right Car to Tow
Not every car makes a good tow car.
Ideal Tow Cars
Look for:
- Lightweight vehicles
- Manual gearboxes (often preferred)
- Strong front chassis points
- Popular tow-compatible models
Things to Check
Kerb Weight
Lighter is usually better.
Manufacturer Limits
Check:
- Vehicle handbook
- Chassis suitability
- Towing conversion compatibility
Ground Clearance
Important for attachment geometry.
Popular Toad Cars
Common choices often include:
- Small hatchbacks
- Compact city cars
- Lightweight crossovers
Choose based on your motorhome’s towing capacity.
Chapter 6: Weight Matters More Than Most Buyers Realise
Understand These Terms
Gross Vehicle Weight (GVW)
Maximum safe loaded weight.
Gross Train Weight (GTW)
Maximum combined weight of:
- Motorhome
- Passengers
- Gear
- Fuel
- Towed car
Towing Capacity
Your motorhome may legally or mechanically limit what you can tow.
Never buy an A-frame before checking this.
Example
If your motorhome can tow 1,500kg:
- Car weighs 1,250kg
- A-frame system weighs 60kg
- Gear in car adds 80kg
Total: 1,390kg
You’re close to the limit.
Margins matter.
Chapter 7: What Makes a Good A-Frame?
Build Quality
Look for:
- Heavy-duty construction
- Corrosion resistance
- Quality welds
- Strong couplings
- Durable finish
Ease of Use
Ask:
- How long does hookup take?
- Is it easy solo?
- How heavy is the frame?
- How simple is storage?
Braking Performance
Critical.
Look for:
- Smooth braking response
- Proven systems
- Emergency breakaway protection
- Minimal false activation
Engineering and Support
Good suppliers offer:
- Vehicle-specific fitting
- Technical support
- Spare parts availability
- Servicing support
- Warranty cover
Chapter 8: Questions to Ask Before Buying
Ask every supplier:
Is it vehicle-specific?
Avoid generic “one-size-fits-all” claims.
How Does The Braking System Work?
Understand it fully.
What Is Included?
Clarify:
- Installation?
- Wiring?
- Brake system?
- Couplings?
- Training?
What Warranty Is Included?
Ask about:
- Frame warranty
- Brake system warranty
- Installation warranty
Are Parts Readily Available?
Very important long term.
Is Servicing Required?
Some systems require regular checks.
Chapter 9: New vs Used A-Frames
Buying New
Pros
- Warranty
- Latest safety features
- Professional setup
- Known history
Cons
- Higher price
Buying Used
Pros
- Lower upfront cost
Risks
- Hidden wear
- Outdated systems
- Missing parts
- Compatibility problems
- Unknown legality issues
If Buying Used Check:
- Couplings
- Wear points
- Brake mechanism
- Corrosion
- Wiring condition
- Service history
- Crash damage signs
Personally, many buyers are better off buying new.
Chapter 10: Installation Considerations
Professional Installation vs DIY
Professional fitting is usually worth it.
Why? Because installation may involve:
- Chassis mounting
- Brake integration
- Electrical systems
- Safety checks
Mistakes can be expensive or dangerous.
Typical Installation Time
Often:
- Half day to two days, depending on the vehicle.
Chapter 11: Common Mistakes Buyers Make
Buying Too Cheap
Cheap can become expensive.
Ignoring Weight Limits
Huge mistake.
Choosing on Price Alone
Support matters.
Forgetting About Servicing
A-frame systems need maintenance.
Assuming Any Car Can Be Converted
Not true.
Not Researching Travel Rules
Especially important for European touring.
Chapter 12: Features Worth Paying Extra For
Sometimes premium features are worth it.
Quick Connect Systems
Faster hookup.
Better Braking Systems
Often worth the money.
Corrosion Protection
Especially for year-round use.
Locking Security Features
Helpful for theft prevention.
Premium Couplings
Can improve longevity.
Chapter 13: How to Compare A-Frame Suppliers
Compare suppliers on:
Reputation
Look for:
- Reviews
- Forums
- User groups
- Longevity in business
Support
What happens after the sale?
Engineering Quality
Ask technical questions. Good suppliers can answer them.
Aftercare
Very important.
Demonstrations
Even better if they offer live demos.
Chapter 14: A-Frame vs Trailer — Which Is Better?
Choose an A-Frame If You Want:
- Faster setup
- Easier storage
- Lower weight
- Simpler touring
Choose a Trailer If You Want:
- Full legal certainty in some regions
- No mileage added to towed car
- Potentially broader vehicle compatibility
There Is No Universal Best Option
There is only the best option for your setup.
Chapter 15: Maintenance Checklist
Inspect regularly:
Before every trip:
- Hitch coupling
- Pins and locks
- Safety cables
- Lighting
- Brake operation
- Tyre pressures on the towed vehicle
Annually:
- Full service
- Brake system check
- Wear inspection
- Corrosion treatment
- Electrical check
Maintenance protects both safety and resale value.
Chapter 16: What a Good A-Frame Setup Looks Like
A good setup should be:
✔ Correctly matched to your motorhome
✔ Correctly matched to your car
✔ Weight compliant
✔ Professionally installed
✔ Easy to connect
✔ Supported by a reputable supplier
✔ Serviceable long term
That is far more important than buying the “cheapest” system.
Chapter 17: Budgeting Example
Example realistic budget:
| Item | Estimated Cost |
|---|---|
| A-frame system | £2,500 |
| Vehicle fitting | £800 |
| Brake integration | £600 |
| Wiring and lights | £250 |
| Annual service | £150 |
Total first-year cost: Approximately £4,300
Plan realistically.
