I am currently at 4.
1. Traeger Timberline 1300- Currently gets the most use out of the four cookers. I'll start it up right when I get home from work and usually cook chicken or pork chops for the evening meal.
2. Kamado Joe Big Joe- I previously owned an XL BGE and loved it but needed more room and sold it. When I saw this at a Costco roadshow, I couldn't pass it up. Main use is steaks, pizza and Rotisserie.
3. Cookshack FEC100- Was my main smoker for a few years and while catering. Around here, more people wanted tri-tip and chicken then pulled pork and brisket, so it mainly got used as a holding oven when we were on location. We would also crank it as high as we could get it to roast root veggies, potatoes, and other sides. It is also nice for large family gatherings. Currently it sits disassembled on my patio. I took it apart for a deep cleaning and now I need to replace the temp probe, door gaskets and repaint the pellet hopper. It is older and originally came with a Traeger controller (before FEC started making the IQ series controllers). I'd love to upgrade to a IQ5 controller but last I checked it was very cost prohibitive.
4. Weber Genesis gas grill. Bought a junker off of Craigslist and refurbished it. Looked brand new when done. Is/was used by the wife to grill burgers, chicken etc. I'll use it to sear a steak if I am feeling lazy.
I have a very small patio dominated by the cookers. I have a portion of my backyard where I would love to make a space for them all, but that will have to wait until I get more time & money.
