Never cooked pork tenderloin that way. I'm sure pork shoulder in a crock pot would make great pulled pork, but I'm always worried that pork tenderloin will dry out whenever I cook it. I made some in my sous vide machine once that turned out great, but with that type of cooking, the meat never goes above the cooking temp., which I'd set at 140°. Then I seared it off in a cast iron skillet to give it a nice crust. I need to do that again. I can pretty much eat as much meat as I want on this diet/cleanse.
