Flat towing (also called "four-down" or "dinghy towing") connects all four wheels of the towed car to the road through a tow bar. Dolly towing loads the front wheels onto a small two-wheel dolly so they rotate, and the rear wheels roll on the ground. Which to use depends almost entirely on your towed vehicle.

⚠ AWD cannot be flat towed or dolliedTrue AWD vehicles (Subaru, Audi quattro, most CUVs) cannot be flat-towed AND cannot be dolly-towed without lifting both axles - that means a full trailer, not a dolly. Confirm in the owner's manual before assuming.

📝 Step-by-Step

  1. Flat tow basicsTow bar (Blue Ox, Roadmaster, Demco) bolts to a base plate on the towed vehicle. Whole car rolls on its own wheels. Lighter setup, no separate trailer to store, drives almost invisibly behind the RV.
  2. Dolly tow basicsA two-wheel dolly carries the front wheels of the towed vehicle. Most FWD cars can dolly-tow. Easier to find a compatible vehicle, but dolly itself is bulky and requires parking and registration in most states.
  3. Vehicle compatibility - flat towMany manual-transmission cars can flat tow. Among automatics: most Jeep Wrangler/Gladiator (4WD with proper transfer case in neutral), Ford F-150 (4x4 with neutral tow procedure), select Chevy 1500s, and a handful of others. Check the owner's manual - "Recreational Towing."
  4. Vehicle compatibility - dollyFWD car: yes. AWD car: NO (drivetrain damage). 4WD with disconnect-able rear: yes. Rear wheels stay on the ground and must be free-spinning.
  5. CostFlat tow: base plate $300-$700 + tow bar $1,200-$2,500 + braking system $1,000-$1,500. Dolly: $1,500-$2,800 for a decent dolly with brakes. Flat tow has higher up-front cost but no storage/registration hassle.
  6. Braking systemsBoth setups need a supplemental braking system on the towed vehicle (legally required in most states). Air Force One, RVi3, and Brake Buddy are the popular options.
  7. ManeuverabilityFlat tow: cannot back up at all - the towed car's steering will turn and you cannot recover. Plan routes to avoid backing. Dolly: also cannot back up.
  8. WearFlat tow: drivetrain spins, transmission fluid circulates (if required by procedure). Some vehicles need to be started and run periodically. Dolly: zero wear on the towed vehicle.

❓ Frequently Asked Questions

What is the easiest car to flat tow?
Jeep Wrangler 4-door, hands down. Drop the transfer case into neutral, ignition to ACC, and tow. It is why the Wrangler is the #1 RV "toad" by a huge margin.
Can I flat tow a Honda CR-V?
No (since 2015). Most modern automatic-transmission unibody crossovers cannot be flat towed without drivetrain damage. Use a dolly (FWD only) or a full trailer.
Do I need a supplemental brake system?
Most states legally require one above 3,000 lb towed weight. Even where not required, the motorhome alone often cannot stop a 3,500-4,500 lb toad in an emergency.
How fast can I drive flat-towed?
Most tow bars and base plates are rated to 65 mph. Some are 70-75. Read the manual. Above the rating you risk separation in an evasive maneuver.
Can I dolly-tow a RWD car?
Yes if the driveshaft can be disconnected, or with a vehicle-specific dolly that supports the rear. Most people use a full trailer for RWD cars instead.
What about a full trailer vs flat tow or dolly?
A full trailer eliminates all wear on the towed vehicle, allows AWD vehicles, and lets you back up. Trade-off: 2,000-3,500 lb of trailer weight, much higher cost, and storage. Best for valuable or sensitive vehicles.
