    All I have read says to remove the driveshaft for all but short trips. This is to avoid excessive wear on the transmission. Of course, should probably drain the transmission oil prior to it being on the dolly, or at least cover the end with a bag while lying on the ground disconnecting (ask me how I know) There may be a proper plug for the output that would be handy. Of course, remember to refill prior to driving. This assumes good structural integrity of the unibody. David
