                                                                                          Doug77 (1433)
                                                            
                          
                          
                                                          "Hide-A-Hitch" and/or or "under the bumper" hitches are attached to the rear end of the frame of vans and trucks so the option is limited to one possibility.
 The only options available are weight capacities (Class A, B or C [I, II, and III -pending brand])
