I have a model 3D on top of a Sears Craftsman roller tool chest, makes it handy with the three pull out drawers to hold supplies in. I also attached a folding large cookie sheet to the front of the smoker which really helps with loading the meats, keeping the drippings off the concrete and off our little dogs back as she loved licking the drippings off the concrete ;-)
The folding table is attached to the tool chest with plywood, adhesive and sheet metal screws, it really works great and I just fold the tray down when I don't need it.
