was reading all the feedback from the other post and had a few ??? .I have a reese class v hitch on a 1997f 250 7.3d , does this w/d hitch slide into the my existing receiver or is it a whole different animal . also while i have this wealth of free info would anyone know if one of those 7x14 dump trailers would be able to hook up to it i need to move some dirt and fill on my property and it seems like i could be much more productive than driving it in my fel thanks guys
