We (self included) frequently lament the thinner, cheaper materials we believe Weber has been moving towards as they have rolled out new versions of the Genesis over the years. Admittedly, this is based entirely on casual observations and a certain amount of bias. It is time to move to a more factual investigation.
A while back, I purchased a caliper with longer extension points making it possible to get measurements of the thickness of fireboxes, hood sides, and, where applicable, stainless tables. I have parts from most of the historical progression of Weber Genesis grills, and my friendly Ace took it in stride when "Jon the Grill Guy" brought his caliper inside to examine a new "Tech" Genesis on their sales floor. They did not have any Genesis II grills left, and I don't have any.
First, I have to make some important observations:

In general, I would say that these results indicate that there has been a reduction in the thickness of a number of components. These findings do confirm that my personal observations that the newest Genesis has very thin stainless shelves and firebox are not without basis. On the other hand, the differences I came up with do not support that the firebox is as thin as it seemed to me when just looking at it in isolation.
As a wild card, I threw in the measurements of a Broilmaster grill I have in my pile of unfinished projects. Perhaps not at all surprising, Broilmaster takes the prize for overall thickest cast aluminum. I don't know that I have ever seen or heard of a Broilmaster that had burn-through. On the other extreme, not listed in my schedule, a Spirit II I also looked at on my Ace store's sales floor turned in the thinnest results for firebox and end caps and basically tied the "Tech" Genesis for the thinnest "stainless" side tables.
Lastly, I included the 1st generation Summit that I am struggling to push over the finish line. The results for it do confirm a very solid build to go along with the substantial amount of real 304 stainless used for many parts. With a reinforced firebox, these are just wonderful grills. I hope to update the thread on that restoration soon. It's a race to get it done before tax season hits full speed.
I don't consider this quick study to be a final statement. More work is needed. Also, if anyone has a Genesis II and a caliper that can measure these components, I am sure we would be interested in what you come up with.

First, I have to make some important observations:
- I did these measurements as honestly as I could, but I did not invest a substantial amount of time. My accuracy would probably have been better had I more time to spend. Also, I don't think variations of .1mm are meaningful as they are probably within my caliper's error threshold.
- Most of the grills I measured had variations, sometimes as much as .3mm, as I tested along one section. There were also some larger differences between the sides vs. the front and back of most of the fireboxes I looked at.
- The older grills I looked at included some very old parts that have been out in the elements for some time. I am not sure how their long-term use and storage affected my measurements compared to the brand new "Tech" Genesis. I also looked at a couple parts that have been sand blasted. That could conceivably reduce the parts thickness.
