Abstract
Abstract A raised front end of a trailer is connected over the top of a sedan by means of a cross bar swivelly connected to the bottom of the trailer and having pins at its ends received in saddles attached to a support frame removably secured across the top of the sedan. The cross frame is connected to the top corner frame portions of the sedan by means of longitudinally spaced brackets that project between the body frame and one or two doors of the sedan, and straddle a body center post if necessary to locate the pivotal support of the trailer over the longitudinal center of the spring center of the sedan.
