I claim the ornamental design for a fitted pickup truck bed covering tarp, as shown and described.
FIG. 1 of the drawings is a perspective view showing the back, right side, and top of a fitted pickup truck bed covering tarp embodying the design of my invention,
FIG. 2 is an elevation view of the back of the fitted pickup truck bed covering tarp;
FIG. 3 is an elevation view of the right side of the fitted pickup truck bed covering tarp;
FIG. 4 is a plan view of the top of the fitted pickup truck bed covering tarp;
