thank you. this looks too much like scooby doo van. it does not look like a food truck. please make 2d art logo. please use vans logo as a font guide. please google image search "food truck" to see what they look like. or have a look here:
first please read all my previous comments first. and then... have a look at logo entry #21. you know how there is a white rail at the bottom of the truck? its a white line that represent the base rail, correct? well i like that. on logo #20, there is a headlamp. i like that too. so please add more stuff like that. for example, maybe add a headlamp, a little back bumper, i think there is also room for passenger window in the front, and rear side mirror. this is what i mean by adding more character and adding more elements of a food truck.
maybe try to add 2 or 3 sunroof panels, for example here:
