I picked up a Char-Broil LP7000 Grill and set up my RK Dum this morning it 
took about 45 minutes to get it set up. I did a burn in then loaded 1# of 
Bolivian Cenaproc followed the profile include with the drum and got A nice even 
Full City ++ roast. Cooled in the Shop Vac/Bucket Bean Cooler it work great. The 
beans cooled in less then three minutes.
 After I cooled the Bolivian I loaded 2#'s SM French Roast and took it to a 
Fast rolling Second Crack. It looks great not one scorched bean. Got to get 
some "Zertex" gloves that spit gets HOT!. I do think I will be upgrading to a 
Gear Motor. I'm am loving this set up 3#'s of coffee roasted in less then an hour.

George this is the same grill I used and your setup looks very similar,
only you placed the thermometer in a better location.  For some reason,
I resisted locating my right behind the handle.  I wish I had, but I seem
to get a good enough reading where it is.  I also like your idea of using
the Diamond lava rocks.  I refitted my diffuser to lower it a little over
an inch, but I kept it.  The only advantage I see is that it is easy to
remove the diffuser and vacuum out the chaff from the bottom of the tub
using the same cordless Ryobi vac I use to clean my Mazzer..
Thanks for sharing the pictures.  I'm about to roast another lb or two
myself.  The only thing I do not fully enjoy is the August heat and
humidity, even when I wait until evening.
