Like Smokin says,I'd never be the one to discourage more toys.
We have cambros,and the 120 quart coolers from Sam's that can hold large sizes and quantity.
Just a thought from my post yesterday,which was in about a $20 cooler.
I like to get mine done several hrs early and foil,maybe with a spritz of apple juice,or some of Smokin's vinegar sauce.
Cooler for several hrs,and pull just before serving.I never worry how long they are in the hotbox,as long as they are temp safe.
As an example, Ribdog and I put a large case of 7 to an eight lb butt in Sat night, about 6-6:30PM around 225º.
They came done about 6:30-7:30 AM.
We double foiled them,into a cooler,and about 6:30 PM Barbara and drbbq pulled them.
They were still too hot to touch.
They were close to perfect.At least 3-4 hrs resting is a great thing.
Just a thought for folks that may not need a holding oven.
