Well I did two turkeys this year. I post the other on a separate subject as I cooked it in the La Caja China. This rotisserie is awesome. It could use a bigger motor but what couldn't?
I set the weber up with coals in both baskets and a pan of water in the middle.
I brined the turkey overnight, dried it off and seasoned the outside just before putting it on the grill.
The turkey went on at 9AM and came off about 11:45 at 172 degrees. I added coals about 20 minutes before it was done but would have been OK if I hadn't.
I also used the Tip Top Temp which did a great job of holding the grill between 380 and 400.
This is such a great setup I may buy another kettle grill just to keep the Rotisserie on all the time.
The Onlyfire did really well and I have now added Nomex to the kettle lid to create a better seal. Something I had been planning anyway.
