Well I'm finally starting on a build after 2 years of research and I know I still may need improvements on my ideas as I go, so any input would be awesome. I have a 250 gal propane tank I got from a local dealer and my neighbor had an old heavy duty trailer that I bought.I'm planing on making my firebox insulated and my RF plate removable as to be able to clean the bottom of the tank if needed. I will add pics ad I go.
