Seriously, I can’t afford to join in the wave of street trucks, that’s a little too much for me to invest in. However, I saw that in London they have street vendors selling Jacketed Potatoes from a table top or cart. Ever seen one of these?

This is an excellent idea to explore. You could do this inexpensively with a propane powered small oven that could be purchased used, but if you want to kick it up a notch, as Emeril Lagasse might say, then you have to check out this towable potato oven that is sold on EBay and other locations now in the US.:It runs about $9500 plus shipping.
