Turn on half the barbeque to low or 300F (150C).
On half of the barbeque remove the grate and place the smoke pouch over the flames to produce smoke.
Oil the remaining grates on the unlit side of the barbeque and place the rubbed pork tenderloin.
Smoke with indirect heat, and the lid closed, for 25 minutes, or until an internal temperature of 135 F (55 C)., turning over once at the ten-minute mark and covering with tin foil.
Remove from the grill and let rest for ten minutes.
