I decided to try my hand at a pair of smoked pork tenderloins yesterday, for the Fourth of July. Being so lean, I was worried they would be dry so I gave them a marinade overnight with apple juice & grape juice the night before. Yesterday I got my rub on, got the smoker to 250 & used apple wood. Took about an hour & a half to hit 145. They were quite excellent! Very juicy & full of great, smokey flavor.
