motorbike dolly

Hi All,
I am picking up my GP from Glasgow next month. What i was thinking of for moving the bike was a motorbike dolly, it bolts on to the the tow bar, the front or back wheel sits on the frame. What my question is will it be ok to use this for towing , will it do any damage if the back wheel is turning in neutral for 200 miles, or would it be better if it was the front wheel, or not atall.
Cheers
