Demco Kar Kaddy SS: Best Premium Choice

Demco engineered the Kar Kaddy SS for those who refuse to compromise on space or quality. The defacto standard for premium towing, this dolly features a folding tongue that reduces its storage length from over 11 feet to just 67 inches. This solves the classic RV park dilemma of where to store the dolly once unhooked.

Standard automatic hydraulic surge disc brakes provide smooth, self-adjusting stopping power without requiring an in-cab controller. The steerable axle tracks perfectly behind the motorhome, virtually eliminating the risk of the towed vehicle clipping curbs on sharp turns. A galvanized finish ensures the entire frame resists rust through decades of road salt and rain.

If the budget allows and campsite storage space is a primary concern, this is the absolute gold standard. It is perfect for full-timers who demand durability, easy storage, and premium tracking. Do not buy this if a basic, budget-friendly pull is the only requirement, but invest with confidence if safety and convenience are top priorities.

Roadmaster Tow Dolly 2050-1: Best Durability

Roadmaster is synonymous with heavy-duty towing infrastructure, and the 2050-1 tow dolly lives up to that reputation. Built from heavy-gauge, powder-coated steel, this dolly resists the flexing and twisting that often plagues cheaper models on uneven terrain. It is designed to withstand thousands of miles of rough highway driving without structural fatigue.

The steering deck pivots smoothly on self-lubricating pads, ensuring the towed vehicle follows the RV’s path without binding. It comes equipped with electric brakes, allowing for precise control of braking intensity directly from the motorhome cab. The heavy-duty ramps are integrated and non-skid, making loading a secure process even in wet weather.

This is the ideal match for the long-haul traveler who puts tens of thousands of miles on the odometer annually. If a rugged, no-nonsense workhorse that will likely outlast the motorhome itself is needed, this is the choice. Skip this if a lightweight, easily maneuverable frame is preferred for manual campsite parking.

Master Tow 80THD: Best Heavy-Duty Option

When towing larger sedans, compact SUVs, or mid-size trucks, standard dollies often run out of weight capacity or physical width. The Master Tow 80THD features an 80-inch wide carrying platform and a generous gross vehicle weight rating of 4,900 pounds. It provides the stability and muscle needed to haul heavier loads without straining the tow setup.

Built with high-strength steel and a durable powder-coat finish, this model features low-profile ramps that make loading low-clearance vehicles much safer. The oval LED tail lights are recessed into the frame, protecting them from accidental damage during loading or tight maneuvers. Its heavy-duty radial tires offer superior heat dissipation during long, hot summer hauls.

For those towing mid-sized SUVs or heavier front-wheel-drive crossovers, the Master Tow 80THD is the most reliable heavy-duty choice on the market. It offers peace of mind when matching larger tow vehicles to a motorhome. Avoid this model if only towing a subcompact car, as the wide track might be wider than necessary for narrow roads.

Stehl Tow ST80TD: Best Value with Disc Brakes

Getting premium safety features without a premium price tag is a rare find in the RV world. The Stehl Tow ST80TD breaks this mold by offering dependable hydraulic surge disc brakes as a standard option at a highly competitive price. These brakes respond automatically to the deceleration of the tow vehicle, providing reliable stopping power without complex wiring.

The dolly features a heavy-duty steel frame coated in an industrial powder finish to resist corrosion and road debris damage.

Universal wheel straps are included, which accommodate a wide range of tire sizes right out of the box.

This unit is perfect for budget-conscious RVers who refuse to compromise on braking performance and safety. It delivers the stopping power of high-end models at a fraction of the cost. Pass on this if a folding tongue or lightweight aluminum frame is a high-priority requirement.

ACME EZE-TOW Tow Dolly: Best Lightweight Pick

Maneuvering a heavy steel tow dolly around a campsite by hand can quickly become exhausting. The ACME EZE-TOW addresses this by utilizing a lightweight, high-strength steel design that weighs only about 400 pounds empty. This makes it incredibly easy for one person to unhook and roll into a storage spot.

Unlike pivoting-deck dollies, the EZE-TOW uses a fixed ramp design where the towed vehicle’s steering wheel remains unlocked, allowing the car’s own steering system to negotiate turns. It comes standard with self-adjusting hydraulic disc brakes, which require virtually no maintenance. The low-profile design also provides excellent ground clearance for highway driving.

If physical strength or campsite maneuverability is a major factor in your decision, this lightweight champion is the perfect fit. It is simple, incredibly durable, and easy to handle alone. However, if locking the steering wheel of the towed car is preferred or required by the vehicle manufacturer, look elsewhere.

Master Tow 77T: Best for Compact Cars

For travelers towing small, fuel-efficient compact or subcompact cars, a massive tow dolly is unnecessary bulk. The Master Tow 77T features a narrower 77-inch width, making it highly nimble and easier to track behind smaller Class C or gas Class A motorhomes. It keeps the overall towing footprint compact, which is a massive advantage on winding scenic byways.

Despite its smaller size, it retains the same high-quality construction as its larger siblings, including a durable finish and easy-to-use ramps. The pivoting top deck allows for tight cornering without scuffing the towed vehicle’s tires. Its lightweight frame means it can be towed easily even by smaller RVs with lower towing capacities.

This is the definitive choice for those towing a Prius, Fit, or other compact front-wheel-drive commuter vehicle. It matches the scale of the towed vehicle perfectly, saving weight and aerodynamic drag. Do not buy this if there is any chance of upgrading to a wider or heavier crossover vehicle in the near future.

How to Choose the Right Brakes for Your Dolly

Selecting the right braking system is the single most important safety decision when buying a tow dolly. Surge brakes operate on a hydraulic cylinder built into the dolly’s coupler. When the RV slows down, the momentum of the dolly pushes against the coupler, automatically applying the dolly‚Äôs brakes. This system is entirely self-contained and requires no electrical connection to the RV cab.

Electric brakes rely on an electronic brake controller installed in the motorhome’s driver cabin. They offer the distinct advantage of adjustable sensitivity, allowing the driver to fine-tune how aggressively the dolly brakes. However, this system requires running wiring from the RV’s dashboard to the rear bumper, adding installation complexity and potential points of electrical failure.

Disc brakes generally offer superior stopping power, run cooler on long descents, and resist brake fade much better than traditional drum brakes. Drum brakes are less expensive upfront but require more frequent adjustment and maintenance. For heavy travel schedules or mountainous routes, investing in surge disc brakes is almost always the safest and most reliable path.

Consider the primary tow vehicle and travel style before making a final choice. If multiple vehicles might tow the dolly, surge brakes offer unmatched versatility since they work with any hitch. If maximum control over braking force in varying weather conditions is preferred, electric brakes paired with a quality cabin controller are the way to go.

Crucial Safety Checklist Before Hitting the Road

Safe towing begins long before the RV leaves the driveway, starting with a meticulous pre-trip inspection. Always verify that the coupler is fully seated on the correct size hitch ball—usually 2 inches—and that the safety latch is pinned secure. Safety chains must be crossed under the tongue in a cradle pattern to catch the tongue if a decoupling occurs.

Tire pressure on both the tow dolly and the towed vehicle must be checked when cold and inflated to maximum manufacturer specifications. Wheel straps must be tightened securely over the tires, and then re-tightened after driving the first five to ten miles. Tires compress and shift slightly as they roll, which can quickly loosen a strap that felt perfectly tight in the driveway.

Ensure the taillights, brake lights, and turn signals on both the dolly and the towed vehicle are functioning in perfect sync with the RV. If the dolly is equipped with a breakaway system, verify that the cable is securely attached to the RV frame, not the hitch itself. This ensures the dolly brakes will lock automatically if the dolly completely separates from the tow vehicle.

Step-by-Step Guide to Loading Your Car Safely

• Prep the Ground: Park the RV and dolly on flat, level ground with the RV’s parking brake firmly engaged.
• Align the Setup: Ensure the dolly is perfectly aligned straight behind the motorhome.
• Clear the Ramps: Lay out the wheel straps and secure the loading ramps, making sure they are locked into position to prevent slipping.

Approach the ramps slowly and drive the front-wheel-drive vehicle onto the dolly in a single, smooth motion. Keep the wheels straight and center the vehicle on the ramps until the front tires rest firmly against the dolly’s wheel stops. Put the towed vehicle in park, engage the emergency brake temporarily, and turn off the engine.

Drape the heavy-duty wheel straps over the tires and winch them down tightly using the integrated ratchets. Once the straps are fully secured, release the towed vehicle’s parking brake and unlock the steering wheel if using a pivoting-deck dolly. Finally, attach the safety chains from the dolly frame to the towed vehicle’s frame or control arms for secondary security.

How to Maintain and Store Your RV Tow Dolly

Regular maintenance is the key to preventing disastrous roadside wheel bearing failures. Wheel bearings must be repacked with high-quality marine-grade grease at least once a year or every 3,000 to 5,000 miles. Regularly inspect the dust caps for leaks and use a grease gun to keep the hub bearings lubricated.

For hydraulic surge brakes, check the master cylinder fluid level before every major trip and inspect brake lines for leaks or corrosion. If using electric brakes, test the magnets and clean any rust off the drum surfaces after periods of prolonged storage. Inspect brake pads or shoes for wear, replacing them before they wear down to the metal backing plates.

When storing the dolly long-term, shield the tires from damaging ultraviolet rays with UV-resistant covers. If possible, store the dolly on blocks to take the weight off the tires and suspension. Store it in a dry, covered area, or use a breathable, waterproof tarp to prevent moisture from pooling on the electrical connections and moving parts.

Investing in a reliable RV tow dolly transforms the travel experience, unlocking the freedom to explore remote destinations without the hassle of driving a massive rig through town. By choosing a model that fits both the towed vehicle and your storage capacity, you ensure that every journey is as safe as it is enjoyable. With proper maintenance and diligent safety habits, a quality dolly will serve as a dependable partner for countless miles of open-road adventure.

Frequently Asked Questions (FAQs)

What is an RV car tow dolly?

An RV car tow dolly is a two-wheeled trailer designed to transport a front-wheel-drive vehicle behind a motorhome by resting the front tires on the dolly frame. The vehicle’s rear wheels remain on the asphalt and spin freely during transit. This setup prevents transmission damage without requiring costly driveline disconnects or baseplate modifications to your towed car. Most units feature integrated ramps, built-in tie-down winches, and payload capacities between 3,000 and 4,900 pounds.

What does a swivel pan car tow dolly do?

A swivel pan car tow dolly uses an articulated rotating plate beneath the vehicle’s front tires to help the trailer pivot smoothly during tight cornering. By allowing the support platform to rotate independently from the dolly axle, this design prevents the towed car’s body from striking the dolly fenders on sharp turns. Swivel pan units also permit the steering wheel of the towed vehicle to remain locked, reducing setup steps compared to fixed-frame dollies that require an unlocked steering column.

How do you load a front-wheel-drive car onto an RV tow dolly?

Loading a front-wheel-drive car onto an RV tow dolly requires aligning the car straight, driving up the ramps slowly, centering the tires, and strapping the wheels securely. First, align the vehicle squarely with the dolly ramps on flat ground. Drive forward until the front tires rest firmly against the dolly wheel stops, then engage the parking brake. Secure both front wheels using heavy-duty tire basket straps, connect safety chains to the vehicle frame, and remember to release the vehicle’s parking brake before departure.

How do you back up an RV with a car tow dolly attached?

Backing up an RV with a car tow dolly attached is generally not recommended because the setup has two separate pivot points that cause rapid jackknifing. Attempting to reverse more than a few feet in a straight line almost always pushes the dolly sideways against the motorhome hitch. If you encounter a dead end or tight RV campsite, the safest procedure is to unhook the towed car completely, roll the dolly aside by hand, and maneuver the motorhome on its own.

Is a car tow dolly or flat towing better for RV travel?

Choosing between an RV car tow dolly and flat towing depends on vehicle compatibility, budget constraints, and whether you plan to tow multiple different cars. A tow dolly is significantly cheaper upfront and works with almost any front-wheel-drive car without permanent modifications. Flat towing allows faster hookups and simpler storage at campsites, but it requires an expensive baseplate kit, tow bar, and a vehicle specifically rated by the manufacturer for four-wheels-down towing.

How much does a reliable RV car tow dolly cost to buy new?

New RV car tow dollies typically cost between $1,500 and $4,500 depending on the braking system, tongue weight rating, and whether the frame uses galvanized steel. Entry-level models with basic idler hubs and no brakes start around $1,500 to $2,000. Premium dollies featuring surge hydraulic disc brakes or electric brakes, articulating pans, and aluminum lightweight construction range from $2,800 to $4,500. Budget an extra $100 to $250 for spare tires, tongue jacks, and heavy-duty replacement ratchet straps.

Why do car tow dolly tires wear out quickly on long highway trips?

Car tow dolly tires wear out quickly primarily due to incorrect tire pressure, overloading past gross axle ratings, or driving at speeds exceeding trailer tire ratings. Small 10-inch to 14-inch dolly tires rotate significantly faster than RV or standard passenger car tires at highway speeds, generating intense heat. To prevent premature tread wear or blowouts, inflate tires to the maximum cold PSI listed on the sidewall, keep highway speeds under 65 mph, and inspect axle alignment annually with a tape measure or alignment gauge.

Are brakes required on an RV car tow dolly in every state?

Tow dolly brake requirements vary by state and province, but most jurisdictions mandate independent brakes once total towed weight exceeds 3,000 or 4,000 pounds. Because a dolly weighing 500 to 800 pounds combined with a 3,000-pound sedan easily exceeds weight exemptions, buying a dolly with electric or surge disc brakes is the safest choice nationwide. States like California and Idaho enforce strict breakaway braking rules for all trailers, making integrated dolly brakes an essential legal safeguard for interstate travelers.
