Thoroughly wash the surface of the potatoes. Dry with paper towels, brush with oil and rub with salt.
Prepare pellet grill for 225 degrees F., using wood pellets of choice.
Place potatoes in the cooker, close the lid, and let them go for 2 1/2-3 hours, or until the internal temperature at the center of the potatoes reaches between 205-210 degrees F.
Once cooked, remove from the grill, and let stand for 10 minutes. Cut open, fluff the cooked flesh, and top with butter, sour cream, bacon, green onion, and cheese. Serve immediately.
