Now that you have the taste for smoked meatloaf, make some from scratch, and smoke them with no pans. The smoke hits them on every side.
I like a 50-50 mix of ground chuck and ground pork. A couple eggs, some bread crumbs, and your favorite herbs and spices -- golden. Let them set up in the fridge for a few hours to firm up.
It's also cheaper, but looking at your setup, I'm guessing money is not an issue. So, the reason to make your meatloafs from scratch is that it is a lot more fun, if you love to cook, and it tastes awesome.
No offense intended. I go the pre-made route from time-to-time when I cook. We don't always have time to go scratch. But, if you have some time, a scratch-made smoked meatloaf is farking awesome. It is one of my favorite comfort foods. That and some mashed potatoes can erase my worst day at work.
