3. The apparatus as set forth in claim 1 , wherein said trailer is of sufficient length to support at least said second truck, said third truck and a fourth truck.
4. The apparatus as set forth in claim 3 , wherein at least a portion of said second truck is supported by said second ramp, and wherein said third truck and said fourth truck are secured to said trailer.
5. The apparatus as set forth in claim 3 , wherein at least a portion of said second truck is secured to said second ramp, at least a portion of said third truck is secured to said second truck, and at least a portion of said fourth truck is secured to said third truck, said second truck, third truck and fourth truck being secured in a partially stacked and partially overlapping relationship with one another.
6. The apparatus as set forth in claim 1 , wherein said second extension member is of sufficient length to provide wheeled access to said rearward bed when said second retractable elevator is in a retracted position that substantially bridges said second ramp and said second extension member to said rearward bed.
7. The apparatus as set forth in claim 6 , wherein said second extension member is securable to said rearward bed to provide wheelable access to said rearward bed to allow movement of one of said plurality of trucks between said trailer and said rearward bed.
8. The apparatus as set forth in claim 1 , wherein said bed extender comprises a fifth wheel assembly.
9. The apparatus of claim 1 , wherein the retractable rear extension is configured for positioning within the trailer when not in use as an extension.
10. An apparatus for compactly transporting a plurality of trucks, said apparatus comprising in combination:
a.) a truck tractor including a horizontal rearward bed for supporting at least a first truck of said plurality of trucks, said rearward bed including:
a first ramp for supporting at least a portion of said first truck of said plurality of trucks;
a first retractable elevator for moving said first ramp between a raised position and a lowered position, said first ramp substantially conforming to a surface of said rearward bed when said first retractable elevator is in said lowered position; and
a first extension member projecting from said first ramp;
b.) a trailer supporting said plurality of trucks, said trailer including:
a second ramp for supporting at least a portion of a second truck of said plurality of trucks;
a second retractable elevator for moving said second ramp between a raised position and a lowered position, said second ramp substantially conforming to said trailer when said second retractable elevator is in said lowered position; and
a retractable rear extension; and
a second extension member projecting from said second ramp, wherein said second extension member is of sufficient length to provide wheeled access to said rearward bed when said second retractable elevator is in a retracted position that substantially bridges said second ramp and said second extension member to said rearward bed; and
c.) a bed extender for coupling said truck tractor to said trailer;
wherein at least a portion of said second truck of said plurality of trucks is supported by said second ramp, and wherein a third truck is partially supported by the second truck and partially supported by the trailer.
11. The apparatus as set forth in claim 10 , wherein said first extension member and said second extension member are hydraulically retractable relative to said first ramp and said second ramp, respectively.
12. The apparatus as set forth in claim 10 , wherein said first retractable elevator and said second retractable elevator include a first hydraulic mechanism and a second hydraulic mechanism, respectively.
13. The apparatus as set forth in claim 10 , wherein said trailer is of sufficient length to support at least said second truck, said third truck and a fourth truck.
14. The apparatus of claim 10 , wherein the retractable rear extension is configured for positioning within the trailer when not in use as an extension.
15. An apparatus for compactly transporting a plurality of trucks, said apparatus comprising in combination:
a.) a truck tractor including a horizontal rearward bed for supporting at least a first truck of said plurality of trucks, said rearward bed including:
a first ramp for supporting at least a portion of said first truck of said plurality of trucks, said first ramp being pivotally connected to said truck tractor and a first extension member for projecting from said first ramp, said first extension member hydraulically retractable relative to said first ramp; and
a first retractable elevator for moving said first ramp between a raised position and a lowered position, said first ramp substantially conforming to a surface of said rearward bed when said first retractable elevator is in said lowered position, said first retractable elevator including a first hydraulic mechanism;
b.) a trailer supporting said plurality of trucks, said trailer comprising:
a second ramp for supporting at least a portion of said second truck of said plurality of trucks, said second ramp being pivotally connected to said trailer and a second extension member for projecting from said second ramp, said second extension member hydraulically retractable relative to said second ramp, said second extension member having sufficient length to provide wheeled access to said rearward bed when said second retractable elevator is in a retracted position that substantially bridges said second ramp and said second extension member to said rearward bed;
a second retractable elevator for moving said second ramp between a raised position and a lowered position, said second ramp substantially conforming to said trailer when said second retractable elevator is in said lowered position, said second retractable elevator including a second hydraulic mechanism; and
said trailer is of sufficient length to support at least a second truck, a third truck and a fourth truck, wherein at least a portion of said second truck is supported by said second ramp, and wherein said third truck and said fourth truck are secured to said trailer; and
a retractable rear extension; and
c.) a bed extender for coupling said truck tractor to said trailer, wherein said bed extender comprises a fifth wheel assembly;
wherein at least a portion of said second truck of said plurality of trucks is supported by said second ramp, and wherein said third truck is partially supported by the second truck and partially supported by the trailer.
