I have a larger roll around charcoal grill (I don't do gas) but it stays in garage most of the time.
However, the free little Weber given to me 7 years ago (used then) still sees the most action. I have resorted to welding sheet metal in the bottom to reduce airflow because the original vents rusted away. I doubt I'll take the time to perfect the large one. No more than we grill I'll just get another Weber when the rack falls in.
