Happy New Year! Hopefully, 2020 will be a gas!
Larry: Thanx for your updated information and recommendation. Down here in San Jose, Costa Rica we have only a dry or rainy seasons in which Green Mold and bugs can accumulate in your BBQ Arsenal in a hurry due to humid conditions. I air-out my Charcoal BBQ's around every two(2) weeks, leave the door off on my WSM when not in use, and do not cover my equipment especially during the rainy season(May-Oct). I do not have a garage space to store my BBQ Arsenal and all my equipment ia kept in a covered patio area.
My thinking on the smaller Weber 2200 is that it will be much easier to maintain than the larger unit but the two-burner Weber 3200 temps me to buy-it based on the ability to do both Indirect and Direct Cooking.
