I have several on low stands with caster wheels.
So far I have cooked with lump and briq once each. I liked the results both times. Limited sample. I just finished it 2 weeks ago.
Mine was built completely weld free. I put the basket together with bolts. I used conduit nuts on the pipe nipples with a little JB weld on the outside.
