When a vehicle needs to move but cannot be driven, a car hauler trailer or tow dolly is the answer. Big Rentals rents both in Laredo for vehicle transport situations of all kinds: a private sale where the buyer is collecting the car, a non-running vehicle heading to a mechanic, a purchased vehicle being relocated, or a cross-border transport need along the I-35 corridor. The first decision is choosing between a full car hauler and a tow dolly, and that choice is determined by the vehicle being transported, not by preference or price.

Car Hauler Trailer vs. Tow Dolly: Which One Is Right for the Vehicle

A tow dolly lifts only the front two wheels off the ground, leaving the rear wheels in contact with the road during transport. That works correctly for front-wheel-drive vehicles, where the driven wheels are the ones in the air and the rear wheels simply roll without transmitting power through the drivetrain. For a rear-wheel-drive or all-wheel-drive vehicle, using a dolly means the driven rear wheels are rolling against the road for the entire haul, which sends movement back through the transmission and driveshaft without the engine running. That causes drivetrain damage that builds with every mile and is not immediately visible until something fails.

A full car hauler trailer lifts all four wheels completely off the road, which makes it compatible with any drivetrain: front-wheel-drive, rear-wheel-drive, all-wheel-drive, and four-wheel-drive. When the vehicle's drivetrain type is uncertain, a car hauler rental is the safe default. Big Rentals rents both car hauler trailers and tow dollies in Laredo, and the vehicle's drivetrain is the starting point for confirming which rental fits.

Ground Clearance and Tow Vehicle Setup

Two other factors worth confirming before the rental date: the vehicle's ground clearance and the tow vehicle's hitch setup. Standard car hauler ramps create a loading angle that most vehicles navigate easily. Vehicles that sit lower than stock ride height, whether from factory sport suspension or aftermarket modifications, can contact the ramp at the transition point before the front wheels clear. Big Rentals has car hauler configurations in Laredo with ramp angles suited to lower-clearance vehicles. On the hitch side, car hauler trailers use a 1-7/8 or 2-inch ball, and the tow vehicle needs the correct size installed before pickup. The combined weight of the trailer and the vehicle on it typically runs between 5,000 and 8,000 pounds, so the tow vehicle's rated capacity should cover that total.
