Does anyone have any experience with this oven or something similar? Considering there are only 3 slots on this I was wondering much you could fit into each tray? Does it require different parchment paper to fit the length/width of the tray? My main question is how much more can fit compared to a normal 1.9cubic foot oven shelf 
Im sure if you look up model it will give you info on shelf dimensions. Which will let you know what will fit inside
Measure inside dimensions & I’ll help
It was a listing on the internet so I didn’t have the dimensions, but I ended up rolling the dice and driving 3 hours to look at it. The trays are absolutely massive and I like it. Thank you for offering the help!
Looks like 7.5cu ft. You can fit about 300-450g slabs on a 7.5 shelf
