for those that haul trailers behind their bikes. dont they make a standard size coupler that is split right after the lock down handle to allow the device to rotate left or right when our bike is on such an angle to allow the install and removal of hitch. i dont want to put a longer kickstand on bike for it to sit up straighter. i know they make a swivel that goes on trailer tongue first then the other half standard coupler goes on. i'ld rather the coupler itself be split.
