i had a quick look at the custom coffee van site.... they dont mention any of the machinery or appliances they use??? strange in short, if your generator or deepcycle batt pack/inverter breaks down,,, income stops!! if your machine runs out of steam or pump over heats,,,income stops!!! in my mind they are two of the most important factors im guessing there starting price of $49,000 is with cheap equipment.. price with better equipment goes up from there?? i mean if they use say Honda or Onan/kubota generators then you would plaster that all over the site.. if you call them ask what machines are being used
