The invention claimed is: 1. A door carrier and mounting device, comprising: a) a first frame for supporting a door comprising; i) a base having a pair of upward facing U-shaped channels, each U-shaped channel having an upper planar bottom in the center thereof and being further characterized by a primary axis running along the center of the upper planar bottom, wherein said pair of U-shaped channels are aligned such that the primary axis of each U-shaped channel is coincident with a the primary axis of the other U-shaped channel, with the U-shaped channels being separated by a gap along the primary coincident axes thereof, wherein a lower portion of a door is supportable by the upper planar bottoms of the U-shaped channels, ii) a plurality of arms attached to and extending laterally outward from opposing sides of said base; iii) a plurality of support members attached to said plurality of arms and extending upwardly substantially parallel to one another; and iv) a plurality of wheels adjustably attached to said plurality of arms disposed distal from a central axis of said base b) a lifting frame having a pair of spaced apart lifting feet capable of being raised from below to above the coincident primary axes of the U-shaped channels, wherein the lifting frame is coupled in vertically adjustable engagement with said first frame for raising a bottom of a door above the upper planar bottom of the U-shaped channels. 2. A door carrier and mounting device according to claim 1 wherein each of the spaced apart lifting feet can be raised and lowered independent of the other lifting foot. 3. A door carrier and mounting device according to claim 2 wherein each of the spaced apart lifting feet is raised by a vertically disposed threaded rod attached to an end thereof. 4. A door carrier and mounting device according to claim 3 wherein each of vertical disposed threaded rods extends through a hollow vertical shaft having a top end, each hollow vertical shaft being attached to the door supporting frame, with the threaded rod coupled in vertically adjustable engagement with said door supporting frame by a nut, said nut being supported by the top end of the hollow vertical shaft. 5. A door carrier and mounting device according to claim 4 and further comprising one or more clamps coupled to the door supporting frame to stabilize a door resting on the horizontal portion of said L-shaped lift member. 6. A door carrier and mounting device according to claim 5 wherein each of the spaced apart lifting feet can be raised and lowered independent of the other lifting foot. 7. A door carrier and mounting device according to claim 1 wherein the spaced apart lifting feet are elongated and have a principal axis disposed perpendicular to the primary axis of each U-shaped channel. 8. A door carrier and mounting device according to claim 1 and further comprising one or more clamps coupled to the door supporting frame to stabilize a door resting on the horizontal portion of said L-shaped lift member.
