Yes, you can put a car dolly on the back of a camper, but it is a complex maneuver that requires careful consideration of your rig's weight ratings, the correct hitch setup, and adherence to state laws. The primary challenge is that you are essentially creating a double-tow setup, which is legally permitted in many, but not all, states. Success hinges on your camper's Gross Combined Weight Rating (GCWR) and the specific hitch receiver strength.
First, you must verify your camper's capability. The frame-mounted hitch on the rear of your camper must be rated for the tongue weight and gross weight of the loaded car dolly. Most factory-installed bumper hitches are not strong enough for this task. You will likely need a professional to install a Class IV or Class V hitch directly to the camper's frame. Next, check your camper's GCWR, which is the maximum allowable weight of the fully loaded camper plus the fully loaded dolly and car. Exceeding this rating is extremely dangerous and illegal.
Legally, double-towing laws vary significantly. While states like California, Texas, and Florida generally allow it (with a total length restriction, often 65 feet), states like New York, Oregon, and Washington strictly prohibit it. You must check the laws for every state you plan to drive through. From a safety perspective, adding length and weight behind the camper's axle affects handling, increases sway risk, and requires much wider turns. Electric brakes on the dolly are highly recommended.
| Key Consideration | Specification / Requirement | Why It Matters |
|---|---|---|
| Hitch Requirement | Class IV or V frame-mounted receiver | Standard bumper hitches fail under dolly load |
| Critical Weight Rating | Camper's Gross Combined Weight Rating (GCWR) | Must not be exceeded by camper + dolly + car weight |
| Typical Maximum Length | 65 feet (total rig length, varies by state) | compliance for double-towing |
| Brake System | Electric brake controller for dolly brakes | Essential for safe stopping distances |
| State Legality | Permitted in many western/southern states; prohibited in several northeastern states | Avoids fines and being forced to unhitch |
Ultimately, this setup is possible but should not be undertaken lightly. Consult your camper's owner's manual, have a professional hitch installer assess your vehicle, and meticulously plan your route based on state laws.

I've done this with my Class A motorhome to tow my sedan. It works, but it turns your rig into a long, slow-moving train. Forget about quick lane changes or tight gas stations. The biggest hassle is checking each state's rules—what's fine in Arizona might get you pulled over in Oregon. It's a solution for a specific need, not something for a beginner to try on a whim. If you're not comfortable driving a big rig, adding a dolly will amplify every handling quirk.

The legality is the real gatekeeper here. You need to research the "double-tow" or "triple-tow" laws for your specific state and any state on your route. Some states base legality on the combined length, others on the type of leading vehicle (e.g., a motorhome might be treated differently than a pickup truck towing a camper). A quick call to the Department of Motor Vehicles in the states you're traveling through can give you a definitive answer and save you a major headache and a potential fine.

Beyond the stuff, think about the physics. You're putting a lot of leverage on the back of your camper. Every bump and sway from the camper is magnified for the car on the dolly. You absolutely need a robust, frame-mounted hitch—the flimsy one meant for a bike rack won't cut it. Also, practice turning and backing up in a huge, empty parking lot first. The turning radius is massive, and backing up is nearly impossible without jackknifing the dolly. It demands patience and constant awareness.

From a pure equipment standpoint, the answer is yes, the hardware exists. But you have to ask if it's the best option. For a front-wheel-drive car, a dolly is okay, but a full four-wheel-down flat tow setup is often more stable and convenient—no loading/unloading the dolly. For an all-wheel-drive vehicle, a dolly might be your only choice without a trailer. Weigh the cost of a proper hitch installation and a quality dolly against the convenience it provides for your specific trip. Sometimes, renting a larger truck to tow the camper and flat-towing the car is a simpler alternative.
