Flat towing, also known as “dinghy towing,” is a popular method among RV owners who want to bring a vehicle along for local exploration after parking their motorhome. While Jeeps are often the go-to choice, many adventurers and vintage car enthusiasts wonder: Can you flat tow a Classic Land Rover Defender behind an RV?
The answer is yes—but there are crucial considerations and proper setup steps required to do it safely, reliably, and legally. Below is an in-depth guide on flat towing your classic Defender, including technical specifications, setup instructions, and recommendations on equipment.
Why Flat Tow a Classic Defender?
The classic Land Rover Defender is not only iconic but also immensely capable. For RV owners who want a rugged vehicle to explore off-road trails, country lanes, and remote destinations, a Defender is an unbeatable companion. Flat towing preserves your RV’s cargo space and allows seamless transitions from highway to dirt road.
However, not all Defenders are created equal in terms of towing practicality. Here’s a breakdown of the key Defender models and their towing suitability.
Weight and Dimensions: D90 vs D110 vs D130
| Model | Curb Weight | Length | Width | Height |
|---|---|---|---|---|
| Defender 90 | ~3,500–3,900 lbs | ~153 in (12.75 ft) | 70.5 in | 77 in |
| Defender 110 | ~4,200–4,600 lbs | ~180 in (15 ft) | 70.5 in | 77 in |
| Defender 130 | ~4,900–5,500 lbs | ~202 in (16.8 ft) | 70.5 in | 77 in |
Note: These weights can vary based on upgrades like roof racks, winches, bumpers, engine conversions, and interior additions.
Why the D90 is the Best for Flat Towing
- Lighter weight: Significantly easier on your RV’s transmission and brakes.
- Shorter length: Easier to maneuver and park.
- Lower wind drag: Especially beneficial when flat towing at highway speeds.
- Soft Top Option: The D90 Soft Top is often the lightest variant, making it arguably the ideal model for flat towing. Plus, once unhitched, it offers an open-air, immersive driving experience perfect for warm-weather exploration.
Step-by-Step: How to Set Up Your Classic Defender for Flat Towing
1. Confirm Your Drivetrain Compatibility
Most classic Defenders—particularly those built before 1999—are equipped with a manual transmission and a part-time four-wheel drive (4WD) system that includes a 2-speed transfer case. This traditional drivetrain configuration is essential for safe and effective flat towing.
Before attempting any setup:
- Verify that your Defender has a manual transmission. Automatic transmissions, especially in older Defenders, are generally not recommended for flat towing unless they’ve been extensively modified with a transmission lubrication pump.
- Ensure the transfer case features a true neutral position (typically marked “N” between High and Low gears).
- It is strongly recommended to confirm whether your Defender’s transmission uses a countershaft lubrication design. Some older manual transmissions rely on engine operation to distribute lubricant, meaning towing without the engine running can lead to gear and bearing damage due to insufficient lubrication. A countershaft-driven lubrication system is more forgiving and may be safer for flat towing.
Proper Flat Towing Setup:
- Transfer Case: Set to neutral. This disengages the driveshafts, preventing drivetrain damage during towing.
- Transmission: Set to neutral for added safety and reduced internal friction.
- Ignition Key: Turn to the first position to unlock the steering wheel. This is crucial to allow the front wheels to follow the RV during turns.
If your steering wheel locks with the key removed, turning the key to the first click without starting the engine will typically unlock it. On some Defenders, removing the key entirely locks the column—so confirm how your specific ignition system functions.
If your Defender does not have a clear transfer case neutral, or if you’re uncertain how your driveline is configured—consult a Land Rover specialist or experienced Defender mechanic before towing. Misconfiguration can lead to catastrophic drivetrain damage or complete transmission failure.
Additionally, keep in mind:
- If your Defender has aftermarket driveline modifications (such as upgraded axles, swapped transfer case, or converted drivetrain), verify with the builder that flat towing remains viable.
- Never attempt to flat tow a Defender with the transfer case in high or low gear—this will rotate the driveline internals without lubrication, leading to excessive wear or failure.
2. Install Proper Tow Points
Defenders don’t typically come with factory-installed tow bar mounts.
- Use reinforced recovery points or custom-fabricated mounts welded or bolted to the chassis.
- Avoid using bumper shackles or hooks not designed for sustained stress.
3. Choose a Tow Bar Compatible with the Defender
Look for an RV-mounted tow bar rated for at least 5,000–10,000 lbs.
Top Tow Bar Recommendations
Blue Ox Avail BX7420
- Rating: 10,000 lbs
- Material: Heavy-duty steel
- Weight: ~45 lbs
- Best For: D110 and D130, or heavily modified D90s
Roadmaster Nighthawk All-Terrain
- Rating: 8,000 lbs
- Feature: Built-in LED lighting and cable guides
- Best For: Any Defender, especially if driving at night is expected
Blue Ox Alpha 2 BX7380
- Rating: 6,500 lbs
- Lightweight and ideal for Soft Top D90s
4. Add Supplemental Stop, Turn, and Signal Lighting
Defender electrical systems are often dated and may not sync with modern RVs. Use external tow lighting systems for safety and compliance.
Top Auxiliary Lighting Kits
Hopkins Tail Light Universal Wiring Kit
- Plugs into RV harness
- Provides running lights, brake lights, and turn signals
- Includes magnetic mounts
CURT Magnetic Towing Light Kit (C-53201)
- No permanent installation required
- LED for low power draw
- Compatible with 4-flat wiring
Blazer International Tow Light Kit
- Durable and waterproof
- Quick setup using magnets
5. Safety Cables and Breakaway Systems
- Required in most states for vehicles over 3,000 lbs
- Connect safety chains from the RV to frame-mounted points on the Defender
- Install a brake-away system that activates the Defender’s brakes if it separates from the RV
6. Use a Supplemental Braking System
Laws in many states require the towed vehicle to have an auxiliary brake system.
Top Pick: Roadmaster Invisibrake or Blue Ox Patriot 3
- Activates brakes proportionally with the RV
- Compact and Defender-compatible
Final Tips for Flat Towing a Defender
- Inspect all bolts, latches, and connections before every tow.
- Disable the steering lock if applicable.
- Check tire pressure regularly—towed vehicles still experience tire wear.
- Always do a short test run before your first long-distance tow.
