You would need to add vents as the propane one doesn't have and air control. The propane one also has a louvered lid which is always open- you may have trouble choking off the fire. Does the propane one have a charcoal grate at the bottom? It would be better to get the charcoal off the bottom surface to preserve the porcelain and let the charcoal breath. Imo, it would be better to sell that on CL for $20-25 and buy a SJ. the jury is split on how much they like the CGA, but if you know how to use it you can get good results.
