Here is a couple pictures of my buddy's new UDS cart is going to use in competition. The frame on the inside is made of 1 in. square tube covered on the sides with aluminum tread plate and then a sheet of stainless steel on the top. He bought three IQ 110s and a couple nights ago we test fired all three of them, they worked amazingly well, about a quarter basket of Kingsford burned for eight hours and then he shut them down. We played with the controllers from 225° up to 350°. He still has a few things to finish on it.
Here are a couple pictures.
