I have that exact grill. I just bought it for $40 on halloween night. She was asking $35, but didnt have change for my $40, so I gave her a $5 tip. Havent fired it up yet, but ordered a cover from Weber last week for it because I couldnt find one anywhere. The cover cost the same as the grill ...
I purchased the floor model - last one they had at a Costco a few years ago. Paid $100 and I used it for a couple of years and sold it to a neighbor. I still visit the grill. Great size, the worktable, and perfect for when the 22.5 wasn't needed. I would not have sold it if I had seen the photos of using it as a base for my WSM. Life goes on...
The photos where somewhere on the TVWBB, the 18.5 base with the WSM on top. It looked a little tall but still a great idea. I will look for the photos.
I can't find the photos but I think they were in one of the threads with "family photos". I'll keep looking. It is a great idea that I'm sure the engineers at Weber would prefer we not try.
If I have to I'll go get the grill, put my WSM on it, and take a photo.
Again, I wouldn't have sold it if I had seen that first. OUCH...
