I have a model 3 smoker and am thinking about purchasing the cart. I contacted the owner to get the dimensions of the cart since they were not on the website and he said it was 12 inches tall. It has shelves that swing up but it seems that they would be awfully low to the ground to be useful. I was wondering if anyone has purchased one of these carts and could give me some feedback as to it's usefulness and if they thought it was worth the price.
