A cargo carrier trailer for movably supporting cargo includes a frame configured to support cargo at the cargo carrier trailer and at least two wheels at each side of the frame. Each of the wheels is rotatably mounted to a respective support arm. The support arms are pivotally mounted to a carriage assembly that is repositionable fore and aft along the frame of the cargo carrier. The support arms are pivotable relative to the carriage assembly and frame to adjust the height and tilt of the frame relative to a support surface. The cargo carrier trailer is readily adapted to position the frame at a lower position for road applications and a raised position for uneven terrain applications. The cargo carrier trailer is adapted to couple to a tow vehicle via a fifth wheel hitch.

The cargo carrier trailer of claim 7, wherein said actuator comprises a double-acting actuator, and wherein said actuator is adapted to extend to raise the forward end portion of said frame and retract to lower the forward end portion of said frame. 9. The cargo carrier trailer of claim 8, wherein said carriage assembly is positionable in a forward position in which an aft end of said cargo carrier trailer is lowered toward the support surface when said actuator extends to raise the forward end portion of said frame. 10. The cargo carrier trailer of claim 1, wherein said support arms are pivoted in response to extension and retraction of a respective support arm actuator. 11. A cargo carrier trailer for movably supporting cargo, said cargo carrier trailer comprising: a frame;a tongue assembly, said tongue assembly pivotably coupled at a forward end portion of said frame and adapted to releasably couple to a fifth wheel receiver of a tow vehicle;a tongue actuator coupled to said tongue assembly and said frame, said tongue actuator adapted to pivot said tongue assembly relative to said frame;a deck mounted to said frame, said deck being configured to support cargo at said cargo carrier; anda carriage assembly for movably supporting said frame and said deck above a support surface, said carriage assembly including a pair of forward support arms independently pivotally mounted to respective sides of said carriage assembly and a pair of rearward support arms independently pivotally mounted to respective sides of said carriage assembly;each of said forward and rearward support arms extending from said carriage assembly and having a respective wheel rotatably mounted at an end thereof, said forward support arms being independently pivotable relative to said carriage assembly to adjust a height of a forward portion of said frame relative to the support surface, said rearward support arms being pivotable relative to said carriage assembly to adjust a height of a rearward portion of said frame relative to the support surface, and said forward and rearward support arms being independently pivotable to level said frame when all of said wheels along one side of said carriage assembly are positioned at a different elevation than all of said wheels along the opposite side of said carriage assembly due to said wheels engaging a non-level support surface; anda carriage actuator, said carriage actuator coupled between said frame and said carriage assembly and adapted to move said carriage assembly fore and aft along said frame. 12. The cargo carrier trailer of claim 11, further comprising a pair of middle-forward support anus pivotally mounted to respective sides of said frame and a pair of middle-rearward support arms pivotally mounted to respective sides of said frame, each of said middle-forward and middle-rearward support anus extending from said carriage assembly and having a respective wheel rotatably mounted at an end thereof, to adjust the height of said frame relative to the support surface. 13. The cargo carrier trailer of claim 11, wherein said forward and rearward support anus at each side of said cargo carrier trailer are cooperatively adjusted. 14. The cargo carrier trailer of claim 13, wherein said cargo carrier trailer is operable to adapt said forward and rearward support arms and wheels at one side of said cargo carrier trailer for a different level of the support surface relative to said forward and rearward support arms and wheels at the other side of said cargo carrier. 15.
