Wife got me the same rotisserie 22 1/2" for Christmas about 10+ years ago. Sooo versatile. I love it and use it all the time. Rarely use the weber for regular grilling - unless it's Prime Rib - it is almost always rotisserie, you get so much flavor and incredible juiciness with the roundie/round. Go get a generic flat square rotisserie basket at Lowe's, that is the only store around here that carries them, about 10 bucks. You can do at any given time 8 - 10 chicken thighs; 2 tri-tips; 2 racks of baby backs; a slab of salmon; a couple of porterhouses, t-bones, or ribeyes... any number of meats that will fit for a fast smoke on the kettle. Indirect, a good 20 min smoke then 20 min to finish depending on the meat and your desired doneness. We use the rotisserie basket for almost everything except whole chickens (you can get 2 on at a time) - nice string job on that puppy by the way!! Oh and we also use just the rod for whole beef or tenderloin or boneless pork roast too. Cornish Game Hens too are great for just the rod, you can get about 4 of those.
The drip pan is great since all the juices of the meat are rolling around so we put wine or beer and fresh herbs into that to help infuse into the meat.
Love love love our rotisserie attachment and any questions you might have feel free to PM me. Would love to share some recipes and tips!!
