Guide to Safe Towing Modifications for Classic Cars

Many RV enthusiasts face a common dilemma: how to safely tow an older vehicle that wasn't originally designed for flat-towing. This guide provides technical solutions for owners who wish to preserve their classic cars while enjoying the convenience of RV travel.

Consider this scenario: an inheritor of a 1990s front-wheel-drive Cadillac wants to maintain this family heirloom during RV trips. However, manufacturer guidelines don't recommend towing this model. This raises a broader question - can vehicles excluded from official towing lists be safely modified for this purpose?

Choosing vintage vehicles for towing offers several benefits. First, the lower acquisition cost and insurance premiums make potential road damage (like paint chips or cracked windshields) more acceptable. Second, simpler mechanical designs often require fewer modifications - some older models don't need battery disconnection or fuse removal procedures.

For front-wheel or four-wheel drive vehicles, Drive Shaft Disconnect (DSC) systems offer an effective solution. Developed by Superior Driveline, these mechanical clutch systems install near the rear axle. A control cable extends to the driver's seat area - pulling it disengages the transmission during towing, preventing internal wear.

Many classic cars with manual transmissions are naturally suited for towing. The key modification involves selecting the correct baseplate. Manufacturers like Blue Ox, Demco, and Roadmaster offer baseplates for vehicles dating back to the 1970s. Once the proper baseplate is installed, universal tow bars, braking systems, and lighting kits can complete the setup.

Automatic transmissions present a unique challenge - they require engine operation for proper lubrication. Remco Towing addresses this with PowerRV pump systems that circulate transmission fluid during towing. These vehicle-specific systems carry a 10,000-mile warranty and are available for models dating to 1996 (with potential support for earlier vehicles).

Remco Towing simplifies the process by offering complete packages including lubrication pumps, baseplates, tow bars, and braking systems. Compatibility exists between different manufacturers' components - Demco and Roadmaster adapters can work with Blue Ox baseplates, while portable brake systems maintain universal applicability.

Beyond lubrication pumps, complete drive shaft disconnection kits provide another option. These systems completely separate the transmission from the wheels, preventing internal component rotation during towing. While Remco no longer offers these, other suppliers continue production.

Even when technical solutions exist, towing non-approved vehicles may void warranties. Always consult vehicle manuals and professionals before modifications. Key components require careful selection:

• Tow Bars: Must exceed the towed vehicle's weight, feature compatible connectors, maintain proper length, and offer adjustability when needed
• Braking Systems: Choose between electronic (precise control), hydraulic (simple design), or inertia (connection-free) systems
• Lighting Systems: Magnetic kits offer convenience while hardwired systems provide reliability

Before each trip, verify:

• Secure tow bar connections
• Functional braking systems
• Synchronized lighting
• Proper tire pressure
• Intact connectors and cables

Through technical solutions like drive shaft disconnects, lubrication pumps, and proper component selection, even vintage vehicles can become reliable RV companions. However, thorough risk assessment and professional consultation remain essential for safe travels.
