Well...that's sort of true. But sort of not. I work for a company
which makes one helluva lot of burners--we make wood, gas, and pellet
stoves and fireplaces.

I promise you that it wouldn't be too hard to design a 30,000 BTU
grill that uses 2 or 3 times as much fuel as, say, a Weber 30,000 BTU
unit. Bad design's easy to do. :\

So, what you said is true if we assume (and that's not necessarily a
good thing to do) that the burners are equally efficient--which of
course is dependent upon their being designed, and made, well.

Uh, we can't change the laws of physics. It takes a given amount of fuel
to make 30,000 Btu of heat. Not every grill will utilize that 30,000 Btu
the same way, but every single one of them will use the same amount of
fuel to generate it. I didn't write the laws of physics, but we all have
to abide by them. Propane has 91,044 Btu per liquid gallon no matter how
good or bad the burner is.

Edwin, isn't it BTU/surface area? When a large grill has 36K BTU doesn't it
heat to a lower temp. than a small grill with the same BTU? That's always
been my assumption.
