Hi I am new to this jewel of a website. I have a browning propane smoker. Here are the questions. 1) smoke leaks from everywhere on this. How do I fix this? 2) the door has two magnets to keep it closed. What can I upgrade to to be able to do away with the magnets? And lastly 3) do these smokers hold enough heat to also use as a electric smoker from time to time for making sausage? Thanks for the time and advice!
