I used a CB cart pretty much identical to that one for my UDS. Worked great. The only problem is that the side tables are weaker without the grill in between to hold them from folding out. You'll need to cut the bars that the grill sat on off to get it to fit. It looked great after a little paint. I even kept the propane burner on the side, but without bracing it I'm afraid with much weight the arms with the table might collapse.
UDS, 22" Weber kettle, Mini WSM, Charbroil gasser and Reverse Flow build in progress
