I claim the ornamental design for a barbeque trailer, as shown and described.
FIG. 1 is a perspective view of a barbeque trailer, showing my new design;
FIG. 2 is a top plan view thereof;
FIG. 3 is a left-side elevational view thereof;
FIG. 4 is a right-side elevational view thereof;
FIG. 5 is a front elevational view thereof; and,

The broken lines in the figures depict environmental matter and form no part of the claimed design. The bottom plan view forms no part of the claimed design.
