Disclosed embodiments of a dolly for towing trailers generally include a main framework, a tongue assembly, stabilizing shocks, an axle, an axle platform, a steering assembly, and/or tire-wheel assemblies. The use of these dolly embodiments reduce the probability of chassis and body damage, enable horizontal alignment of the trailer for level towing and greater weight distribution, and provide self-steering of the dollies as the towing vehicle turns or backs up.
