Flat towing — pulling a car behind a motorhome with all four wheels on the ground — is how most Class A and Class C owners bring a "toad" along without a trailer or dolly. The tow bar is the physical connection point, and the difference between a good one and a mediocre one shows up every single time you hook up: a quality tow bar with non-binding latches releases cleanly even at an angle on uneven ground, while a budget unit can bind up and leave you wrestling with it at exactly the moment you're ready to head out.
Motorhome-Mounted vs Vehicle-Mounted
Most quality tow bars mount permanently to the motorhome's rear hitch receiver and fold up against the back of the RV when not towing — the more common and generally preferred setup, since the tow bar travels with the motorhome and stays out of the towed vehicle's way. Vehicle-mounted tow bars, which stay attached to the toad instead, are less common but can make sense for RVers who tow the same vehicle behind different motorhomes over time.
What Actually Separates Tow Bar Quality
Non-binding latches: This is the single feature experienced flat-towers care most about. A non-binding design releases even when the RV and towed vehicle are at different angles — parked on a slope, or after a turn that leaves the connection under tension. Older or budget designs can bind under exactly those conditions, turning a routine disconnect into a frustrating struggle.
Weight capacity margin: Match the tow bar's rated capacity comfortably above your specific towed vehicle's actual weight, not right at the edge. Many experienced RVers follow an informal 80% rule — staying meaningfully under the tow bar's max rating — for the same safety-margin reasoning that applies to trailer hitches.
Self-aligning vs fixed arms: Self-aligning tow bars automatically center themselves during hookup, which is a meaningful convenience if you regularly hook up solo without a second person guiding the approach.
Our Top Picks
Blue Ox Avail Non-Binding Tow Bar
One of the most consistently recommended tow bars among flat-tow specialty shops, with a swivel head joint that lets the arms twist for easier alignment and long arms that help the towed vehicle track cleanly through turns. A strong default choice across most common toad vehicles.
Non-binding disconnect even at odd angles · High weight capacity · Widely compatible with Blue Ox baseplates
Premium price point · Weighs enough that hookup takes a bit of physical effort
Roadmaster Nighthawk All-Terrain
Roadmaster's premium offering, standing out specifically for integrated LED strips on both arms that make low-light hookups meaningfully easier — a genuinely useful feature not every competitor offers. The Freedom Latch design releases with minimal force even under tension.
LED-lit arms for nighttime hookup · Very low force required to release the latch · Corrosion-resistant stainless and aluminum construction
No rubber boots on the arms, so dirt exposure needs more attention · Among the pricier options in this category
NSA Ready Brute Elite II
A genuinely different approach that combines the tow bar and a mechanical supplemental braking system into one unit, using the towed vehicle's own momentum to activate its brakes during stops. Appeals to RVers who want to simplify their flat tow setup into fewer separate components.
Combines two systems into one purchase and install · Mechanical braking requires no separate battery or electronics · Simplifies overall setup
Less adjustable than dedicated electronic braking systems · Mechanical design has a learning curve for proper adjustment
CURT Rambler Tow Bar
The value-oriented pick, with patent-pending non-binding latches that perform close to premium-tier competitors at a meaningfully lower price. Compatible with both CURT and Blue Ox baseplates, which keeps your options open if you switch baseplate brands down the road.
Strong value relative to premium competitors · Non-binding latches work as advertised · Compatible with multiple baseplate brands
Self-alignment slightly less smooth than top-tier Blue Ox or Roadmaster models · Fewer premium extras like integrated lighting
Matching a Tow Bar to Your Toad
Lighter, common toad vehicles — compact SUVs and midsize trucks — are well served by any of the mid-range options here with comfortable margin below the rated capacity. Heavier toads, including full-size trucks and larger SUVs, need a tow bar rated meaningfully above the vehicle's actual weight, which points toward the higher-capacity end of the Blue Ox and Roadmaster lineups rather than budget or universal-fit options.
Frequent flat-towers who hook up and disconnect often, especially solo, get the most day-to-day value from a genuinely non-binding, self-aligning design — the time and frustration saved over dozens of hookups across a season adds up to real value beyond the sticker price difference.
Baseplate Compatibility Is Vehicle-Specific
A tow bar is only half the equation — it connects to a baseplate that's permanently mounted to the towed vehicle's frame, and baseplates are engineered specifically for each vehicle make and model, not universal. Before buying a tow bar, confirm a baseplate kit exists for your exact towed vehicle from the same brand or a compatible one, since availability varies by vehicle popularity — common toad vehicles like Jeep Wranglers have baseplates from nearly every major brand, while less common vehicles may have limited options.
Baseplate installation typically involves some combination of drilling, trim removal, and occasionally minor bumper modification depending on the vehicle. This is the part of a flat tow setup most RVers choose to have professionally installed, even those comfortable with other DIY automotive work, simply because getting the fit and alignment right the first time avoids expensive rework later.
Storage and Weather Exposure
Motorhome-mounted tow bars that fold up against the rear of the RV when not in use are exposed to road grime, weather, and UV over time, which is why premium models with rubber boots over the telescoping arms hold up better long-term than exposed designs. A simple tow bar cover, a low-cost accessory most manufacturers offer, meaningfully extends the life of an exposed unit and is worth adding regardless of which specific tow bar you choose.
Wiring and Lighting Requirements
Beyond the physical tow bar connection, most jurisdictions require the towed vehicle's taillights, brake lights, and turn signals to mirror the motorhome's while towing, since the towed vehicle's own lights are typically not visible or relevant from directly behind. A wiring kit — either a magnetic-mount light bar for occasional towers or a permanent wiring harness tied into the towed vehicle's factory lighting for frequent towers — is a required companion purchase alongside the tow bar and baseplate, not an optional extra.
Diode-based wiring kits, which isolate the motorhome and towed vehicle's electrical systems while still syncing the lights, are generally preferred over simpler splice-in kits since they avoid the risk of feedback between the two vehicles' electrical systems. Most tow bar manufacturers sell a matched wiring kit alongside their tow bar and baseplate products, which simplifies compatibility questions considerably compared to sourcing wiring separately.
Test all lighting functions — brake lights, turn signals, and running lights — during the same pre-trip check as your braking system, since a wiring fault is just as much a safety and legal concern as a braking issue, and the two systems are worth verifying together rather than as separate afterthoughts.
Frequently Asked Questions
Can any vehicle be flat towed?
No — not every vehicle is rated by its manufacturer for flat towing, since it depends on the transmission and drivetrain design. Always check your specific vehicle's owner's manual or manufacturer specifications for flat-tow (four-down towing) approval before setting up a tow bar system.
Do I need a supplemental braking system in addition to a tow bar?
In most states, yes, it's legally required above certain towed vehicle weights, and it's a meaningful safety improvement regardless of legal requirements — a tow bar alone provides no braking assistance from the towed vehicle, putting the full stopping burden on the motorhome's brakes.
How much does a full flat tow setup cost beyond the tow bar itself?
A complete system includes the tow bar, a baseplate kit specific to your towed vehicle, a supplemental braking system, and wiring for taillights — budget for all four components together rather than just the tow bar price when planning a flat tow setup.
Is professional installation necessary for a tow bar and baseplate?
Baseplate installation often involves some vehicle-specific drilling or trim removal, which leads many RVers to have it professionally installed even if they're comfortable with other DIY projects. The tow bar itself, once the baseplate and hitch receiver are in place, is generally straightforward to attach without professional help.
