Hi David,
Welcome to the Family !
For any meats you place in your WSM, there's no need to turn them. At the very most one need move the meat a maximum of 3 times during an entire cook... once to place it in the WSM, once (only if using the foiling method) to foil the meat, and finally to remove the meat from the WSM. There might be times, in the future, where you may want to move the meat an additional time, let's say from the top to the bottom grill, when making room for other meats on the top grill.
Ahhh... internal temperature. Good as an indicator of what is happening but is not an indicator of BBQ tenderness. Only a physical test will tell when tenderness has been reached. And, if you were to take the internal temperature at the point were tenderness is reached, it would differ from cook to cook and from meat to meat.
