Can someone point me in the direction of finding the internal dimensions of the current model PK100 smoker? I see the external dimensions on the website and it looks like the width and depth should be close to the 17x18 Inch rack size, but I see no mention of the internal ceiling to floor, distance between the ceiling and the bottom catch tray, and the distance between shelves.

I currently have a Cookshack smoker I bought in 2006 and usually do 4 butts at a time for small catering events and family gatherings. I am looking for a larger Cookshack type smoker that I can hang summer sausage in during deer season. I would like to do the 20 inch length casings and hang them from the top shelf like I have seen others do on this forum.
