As whacky as your suggestion sounds, it may have merit. It would certainly have a distinctive appearance and set our food truck apart from the others. Would be great if the food theme was seafood or Cajun crawdad/shrimp boils.
Haha … whacky yes. Just tell everyone that you are always ready to go fishing. A boat on top can just look like its being hauled around. … But I think a flat bottom aluminum john boat with the bow to the front could look like a normal roof extension. All the bracing and skin is ready in place just attach to the top of the truck.
… just a spur of the moment ‘whacky’ idea … oh well I go back to my banana plantation here in south Georgia.
