An A-frame is a rigid triangular towing bar that attaches to the front of a car being towed flat (all four wheels on the ground) behind a motorhome, without using a trailer or dolly.
A-frame towing requires the towed vehicle to have a flat-tow rating from the manufacturer. Popular among full-time motorhome travelers in North America. Legal in most US states; regulations vary across Europe.
