Outstanding first post! WELCOME to the LTBBQ family.
I believe that the diversity of experience here can help you with enough information so that you can find the right pieces of outdoor cooking gear for your needs.
And - our Site Sponsors here have their own thread sections where you can post questions about their offerings. We have been very selective with the companies we allow to become site sponsors on LTBBQ, so you can be confident that they all offer quality, and great customer service.
One type of cooker that I did not see on your list that I can recommend you explore for some of your needs is a pellet grill/smoker. It took me a long time to accept this kind of cooker as a method that I could feel good about using.
But, once I did - I will never go back.
I also have gas, gas infra red, and a Pit Barrel Cooker for charcoal. And - they all have benefits in one or more areas.
It would be a great thread for you to post your outlined needs and request input. If you post this in the General Discussions, it will be seen by more folks, and you will get a lot of quality advice for sure.
We are happy to have you here. Never be afraid to ask any question, or offer your input. We all refer to the only real 2 rules on LTBBQ : 1. The Golden Rule in our interactions with one another. 2. Have Fun!. Yeah - it is a rule here
...relax, and have fun!
