thank you people for the good wishes!!!!!
so to answer some questions:
the oven internal diameter is 90 cm
the cast high aluminia and ss needles, isolated with ceramic blanket and boards
the base with firebricks...
the idea is to make a little business me and my wife
streets hier are more than bad yes
the holes and stones sometimes 4 - 6 inch deep or high so I will not run with the oven no
but drive in first gear, or second, for the first 10 kilometers till I reach the pavement street!!!!! It will be an adventure yes. The trailer suspension goes smooth enough I hope
