There are some cool mods that do work.
I use super heavy duty foil in the bottom of the drum, a "mod" to aid in cleanup. Every few months, I remove the foil and replace. Saves washing the drum.
I have seen guys screw 3 L-hooks into the fire basket sides, then use U bolts on the top 3 grate bolt areas. They hang the fire baskets from the L hooks in the U bolts and put a grate over them, so they create a grill/smoker combo using the same barrel. That is a neat mod that sort of makes it like an Egg in versatility.
The fat belly mod saves a lot of bending to adjust the airflow.
I also added a grate to hold an aluminum foil water pan.
But the basic design -- that is tried and true.
