A trailer dolly can include various features to be adjustable between a manual configuration and a vehicular towing configuration. In the manual configuration, a user can manually maneuver the trailer dolly to position the trailer, such as by using one or more retractable handles. Where the user desires to maneuver the trailer with a vehicle, the trailer dolly can be adjusted to the vehicle towing configuration. In an example, the trailer dolly can be coupled to the vehicle with a second hitch attached to the trailer dolly, the second hitch located distally along the tow bar with respect to the trailer hitch supporting the trailer load. Accordingly, the trailer dolly can be used for both manual and vehicular applications and the user can transition between the manual and vehicular configurations while the trailer is hitched to the trailer dolly.
