The shaft bolt  49  is secured on one end by a head  47   a  and the other end by shaft nut  47   b , allowing the hourglass roller  41   a  to rotate as the winch line  33  in  FIG. 2  moves over the hourglass roller  41   a  to the rear end  23   b  of the recreational vehicle  18  and is retracted back towards the front end  23   a . Referring to  FIGS. 6A and 6B , the “L” brackets  43  can be mounted to a base plate  44  and secured to the roof  20  and the roll cage  21  of  FIGS. 1A and 1B  by a roof bolt  38  through the first leg  45   a  of each ‘L” bracket  43 . Looking to  FIG. 2 , the base plate  44  is centered on the vehicle longitudinal axis  25  and the base plate  44  runs from the roof forward edge  23   e  to the roof rear edge  23   f.    
         [0036]    Looking again to  FIG. 6C , the hourglass roller  41   a  comprises a first disc portion  70  adjacent to a first portion  72  that is conically shaped and adjacent to a uniform circular middle portion  74  that is adjacent to a conically shaped second portion  76  that is adjacent to a second disc portion  78 ; the middle portion  74  being cylindrical and running from the first portion  72  to the second portion  76 ; the first portion  72  and the second portion  76  configured to cradle the winch line  33  of  FIG. 2  onto the middle portion  74 . The first portion ( 72 ) and the second portion ( 76 ) tapering down from the first disc portion ( 70 ) and the second disc portion ( 78 ), respectively, to the middle portion ( 74 ). 
         [0037]    Referring to  FIG. 7 , an elongated cylindrical rod, the cylindrical roller  41   b , may be mounted between the two “L” brackets  43  of the guide support  40   b  of the each guide, such as the top forward guide  14 , and the cylindrical roller  41   b  disposed placed to rotate on the shaft bolt  49 . The cylindrical roller  41   b  may also be removed and the winch line  33  allows to slide over the shaft bolt  49 . 
         [0038]    Looking to  FIGS. 8A, 8B, 9A, and 9B , and more particularly  9   c , the retaining means  40   c  may be a two retaining bars  42   a  that are “L” shaped each having a long leg  42   a   1 , a short leg  42   a   2  and a distal end  42   c . The short leg  42   a   2  is mounted on the “L” bracket adjacent to the second leg  45   b  and perpendicular to the first leg  45   a . When the retaining means  40   c  is two retaining bars  42   a , the retaining bars  42   a  can be mounted on the front guide  12  and the top rear guide  16  as shown in the top forward guide  14  in  FIG. 9C  disposed placed so that the winch line  33  to be inserted around the distal end  42   c  of each retaining bar  42   a  to ride on the hourglass roller  41   a  of the guide means  40   a . When the two retaining bars  42   a  are used, one on each “L” bracket  43  as shown in  FIGS. 9A and 9C , the retaining bars  42   a  are mounted parallel to each other with the distal end  42   c  of the each retaining bar pointed opposite the distal end  42   c  of the other retaining bar  42   a . This allows the winch line  33  to be inserted around the distal end  42   c  of the each retaining bar  42   a .  FIG. 10  shows the retaining bars  42   a  used with the top forward guide  14  of  FIG. 7 . 
         [0039]    Referring again to  FIGS. 1A, 1B, and 2 , the bed loader  10  of this invention is made to use of the winch  24 , winch drum  32   a , winch line  33 , and cable hook  34  provided on many recreational vehicles  18 . The winch  24  performs a key role and is an indispensable component for operating the bed loader  10 . It will be further appreciated that the bed loader  10  can be used for many purposes other than loading game animal in the bed  22 . For example, the winch  24  on the front end  23   a  of the recreational vehicle  18  can be used with the bed loader  10  to load/pull items such as sacks of sand and the like and other objects, by utilizing the winch  24  and the winch line  33  in combination with the front guide  12 , the top forward guide  14 , and the top rear guide  16  of the bed loader  10 , in the same manner described above with regard to the handling and loading the deer  34   a . Since the top rear guide  16  between the front wheels  25   a  and the rear wheels  25   b  of the recreational vehicle  18 , the recreational vehicle  18  is relatively stable when a heavy load, such as the deer  34   a  is attached to the winch line  33 . The recreational vehicle  18  that has four wheels is much more stable and is a preferred vehicle for installation and use of the bed loader  10 , although the bed loader  10  may be mounted on a three wheel recreational vehicle (not shown). 
         [0040]    Although the present invention has been described in considerable detail with reference to preferred versions thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein. Various deviations and modification may be made within the spirit and scope of this invention without departing from the main theme thereof.
