If you give up now, you may never know the taste of excellent smoked ribs.Once you have smoked your own excellent ribs, you will need the ex to hold on to your feet to keep you from floating away in your own heavenly flight. You can do it. Read up a lil on some of the mods for your type of smoker, get a good therm that will give you temp at the grate where your food is. Learn fire management, even if it means a couple dry runs after work, with no food, just fire training(nothing to lose, everthing to gain). Take some temps during these trial runs, and fiddle with your smoker to tune it to what ya need.
Then you can feel more confident about your equipment,put some good meats into it, and enjoy the smoking experience, while relaxing and learning.
Too many good people on this site to let ya just fade away frustrated.We will help ya , and all we ask is, let us. Weeks from now you will be chuckling about this, and posting some good Q-views, and maybe even helping others who need it.
Hang in there.
