Got a call today from a guy in Dalaware today, somehow he used one of my smokers last week and is asking me to build him a 500 gallon smoker. I really don't like building anything over a 250, plus dealing with someone that far away would be too much a pain. This is, after all , just a hobby for me. Is anyone here interested in a potential customer, before it turn him away? He says he will locate tank , purchase trailer, and all materials up front. Let me know.
