Agree with Arrested Development and I would also add What We Do in the Shadows

Smoke Roasted Pork Tenderloin
#foodstr
Rub
Rub:
2 tablespoons paprika
4 tablespoons coconut sugar
1½ tablespoons kosher salt
1 tablespoon fresh ground black pepper
1/2 tablespoon chili powder
1 tablespoon garlic powder
1 tablespoon onion powder
1 tablespoon ground mustard
½ teaspoon cayenne - optional for this cook
2 pork tenderloins trimmed and silver skin removed
About two hours before cooking
Pat dry
Season with Rub and let rest for at least two hours
When it’s time to start grilling:
Fire up grill / smoker
When appropriate for your grill add a mild wood like pecan. Once up to temp (350)
Smoke/Roast and pull off a little early to let rest to 145. I like this cooking tenderloin at this temp because I think searing becomes optional. If you want to sear go ahead and you can even take your temperature all the way down to 250
If sear is desired: Once you have removed tenderloins from the grill, sear for one minute per side in a hot cast iron pan check after 30 seconds to be careful not to let sugar burn 
Not that this is going to instantly change your problems but I found this book helpful and it’s a very quick read
