Choosing the right tow bar for your motorhome isn’t just about picking something that “fits.” It’s about legal compliance, safety, towing capacity, and how you plan to use your motorhome. Considering whether you need a motorhome towbar is also crucial for planning your travel. Whether you want to tow a car, carry bikes, or pull a trailer, this guide will walk you through everything you need to know.
🚐 Why Fit a Towbar to a Motorhome?
A tow bar transforms your motorhome into a far more versatile vehicle. With the right setup, you can:
- Tow a small car for day trips
- Carry bikes, scooters, or storage racks
- Tow a trailer for extra gear
Many motorhome owners choose to tow a car so they can explore tight roads and towns without moving the entire vehicle. ()
⚖️ UK Law: What You MUST Know First
Before choosing a tow bar, UK regulations are critical:
- Post-2012 motorhomes (April 2012 onwards) must use a type-approved tow bar (Regulation 55) if towing anything. ()
- Tow bars must meet safety standards and be correctly fitted, or you risk fines and penalty points. ()
- If towing over 750kg, your trailer must have brakes and a breakaway cable. ()
👉 In short: if your motorhome is modern, you cannot just fit any tow bar—it must be certified for your vehicle.
🔧 Types of Motorhome Towbars
1. Fixed Towbars (Permanent)
Best for: Regular towing (trailers, cars)
- Always visible and ready to use
- Strong and cost-effective
- Ideal for frequent travellers
👉 If you’re towing often, this is usually the most practical choice.
2. Detachable Towbars
Best for: Occasional towing with a cleaner look
- Tow ball can be removed when not in use
- Maintains vehicle aesthetics
- Slightly more expensive
👉 Great if you don’t want a permanent fixture on your motorhome.
3. Retractable / Swivel Tow Bars
Best for: Premium convenience
- Hidden when not in use
- Swivels out when needed
- Higher cost but very sleek
🚗 Towing a Car: Do You Need an A-Frame?
If you want to tow a car behind your motorhome, you’ll likely need an A-frame system.
What is an A-frame?
An A-frame attaches to the front of a car, allowing it to be towed like a trailer. ()
Pros:
- No need for a trailer
- Lightweight and compact
- Easy to store
Cons:
- Must comply with full trailer regulations (brakes, lights, etc.) ()
- Legal rules can be complex, especially in Europe
- Not all cars are suitable
👉 Important: When using an A-frame, your car is legally treated as a trailer in the UK. ()
⚙️ Key Factors When Choosing a Towbar
1. Motorhome Age
- Pre-2012: More flexibility
- Post-2012: Must be type-approved
2. Chassis & Structure
Some motorhomes need chassis extensions or reinforcement before fitting a tow bar. ()
3. Towing Capacity
Check your:
- Gross Train Weight (GTW)
- Maximum towing weight
👉 Never exceed these limits—it’s illegal and unsafe.
4. Intended Use
Ask yourself:
- Towing a car? → Tow bar + A-frame
- Towing a trailer? → Standard tow bar
- Carrying bikes only? → Tow bar (approval less strict but still recommended) ()
5. Electrical Connections
Modern setups require:
- 7-pin or 13-pin electrics
- Integration with vehicle lighting systems
💰 How Much Does a Motorhome Towbar Cost?
Typical UK costs:
- Tow bar: £300–£800
- Installation: £300–£1,000+
- A-frame system: £1,500–£3,000
Costs vary depending on:
- Motorhome size
- Complexity of installation
- Electrical setup
⚠️ Common Mistakes to Avoid
- ❌ Fitting a non-approved tow bar on a modern motorhome
- ❌ Ignoring weight limits
- ❌ DIY installation without expertise
- ❌ Not checking A-frame legality abroad
🧠 Expert Tip
Even a high-quality tow bar can be unsafe if poorly installed. Many experts recommend using professional fitters to ensure compliance and safety (and to avoid MOT issues later).
✅ Final Thoughts
So, what tow bar do you need?
- For most modern motorhomes: A type-approved tow bar is essential
- For towing a car: Combine your tow bar with an A-frame system
- For occasional use: A detachable tow bar is a great balance
- For frequent towing: A fixed tow bar is the most practical
Ultimately, the right choice depends on how you travel, what you tow, and your motorhome’s specifications.
