Hey Two: I took my cart to a gas place here they work on fireplaces and grills and stuff. The guy there told me that he could add more of the same type of burners to the cart, but couldn’t tell me a price or if they could replace the burner system with something else. Said his boss probably could tell me that but he wasn’t there. Don’t know if you have a place similar to this in PA, but you could check them out if you do. I think I am going to go with what I have right now because I’ve had to dump enough money into the regs and license and insurance just to start. I was going to get a full spillage pan at the restaurant supply place, but their’s is the standard size and only fits 3 1/3 pans instead of 4. Would probably have to get one from All American that would probably cost a fortune. Might try using 1/3 pan on bottom with smaller pans inside to create a double boiler type of situation, like was mentioned above. This is my first time, so I have all sorts of things to try. Thanks for letting me know about those stickers, I bought mine second hand and didn’t know that.
