Petunia has a lot of tweaks that really impressed me. What you don't see in the pictures is the platform on the other side of the firebox to keep a pot of hot water on for cleaning. The smoker is also off set on the trailer to allow you to stack coolers on the other side.
A lot of thinking (and drinking) went into makeing petunia from what I have been told.
I still think you need some chrome rims to trim it out!
