Tow Dolly vs. Car Hauler: Which Rental is Right for Your Vehicle?

Q: Can you put an AWD car on a tow dolly? A: No. A tow dolly only lifts the front two wheels off the ground — the rear wheels keep turning and rolling down the highway for the whole trip. On a front-wheel-drive car that's usually fine, since the drive wheels are the ones sitting on the dolly. But on an all-wheel-drive or four-wheel-drive vehicle, all four wheels are mechanically linked through the transfer case or center differential. Towing one with the rear wheels spinning free on the pavement can burn up the transfer case, transmission, or differential in a matter of miles, and most manufacturers explicitly warn against it. If your vehicle is AWD or 4x4, the safe answer is a car hauler, not a dolly. Tow dollies and car haulers both get a vehicle from point A to point B behind another vehicle, but they work on opposite principles. A dolly cradles the front wheels and drags the rear wheels along the ground. A car hauler — a flatbed trailer with ramps — lifts the entire vehicle off the road so none of its wheels touch pavement. That single difference drives almost every other tradeoff between the two. Q: Is it safer to use a car hauler or a tow dolly? A: A car hauler is the safer choice for most renters. Because the vehicle rides fully off the ground, there's no risk of drivetrain damage regardless of the vehicle's drivetrain layout, no concern about tire wear on the dragged wheels, and no worry about a dolly tire blowing out under a wheel that's still bearing load. Car haulers also tow flatter and more predictably at highway speed since the load is centered and low, rather than pivoting on a small two-wheel dolly behind your bumper. The tradeoff is size: a car hauler like our 22-ft wood deck trailer is longer and needs more room to maneuver and park than a compact dolly, so backing into a tight driveway takes a bit more practice. Cost is the other side of the comparison. Dollies are cheaper to rent and lighter to tow, which makes sense for a short, low-stakes trip with a basic front-wheel-drive commuter car. But once you factor in the risk of drivetrain damage on the wrong vehicle, or the extra time spent double-checking tie-downs on a dolly, many renters find the car hauler is worth the difference — especially for a car you actually care about, a non-running vehicle, or anything with all-wheel drive. Q: What are the dimensions of a typical car hauler rental? A: Our open-deck car hauler runs 22 feet of deck length on a tandem axle, rated for 9,900 lbs of cargo capacity, with steel loading ramps and tie-down points at all four corners. That's enough room for a full-size sedan, pickup, or SUV with margin to spare, and the tandem axle keeps the ride stable at highway speed even with a heavier vehicle loaded on. A 22-ft deck also gives you space to carry a car alongside smaller cargo like tires or a spare set of wheels if needed. If you're still not sure which option fits your situation, the safest default is the car hauler — it protects every drivetrain type, keeps tire wear off the equation entirely, and gets your vehicle there without touching a mile of road.
