Mine was a Good Humor style ICE CREAM truck and yours is a Mr. Softee style. Loved the interior, it reminded me of how Candice Olsen of Candice Tells All (HGTV) had a small kitchen to redesign and she used a small food truck vendor for inspiration. You have the right elements in your interior.

my girlfriend bought me the clown,so i decided on using it for my icecream truck,already planned in my mind,i originally thought of using a girl fig,but i think overall this fits even better! i had no previous idea ,as to the top emblem,sign,so the trumpet seemed good!
