Suzie-q,
I placed my father-in-law's #1 on a commercial grade wire cart I purchased at Sam's. It worked great. The smoker and cart are completely stable and the ability to adjust the height of the individual racks will allow you to get the height of the smoker nearly perfect for you. Plus, the extra shelves are handy for storing your wood, unused smoker racks, etc...
