After reading through the archives on here, it looks as if I am going to go with one of the hitch racks from etrailer.. I was originally looking for a 3 bike trailer, but seeing they have a 4 bike could be very useful at times. I am afraid it might extend out too much or??

Who uses a 4 bike hitch rack on here? How far does it extend? Any thoughts , comments, or recommendations?
