Long hours are the norm when owning a food truck business. With shopping, prep, marketing, event booking, cleaning, truck maintenance, accounting and tax obligations, etc., this is more than a full-time job.
Competition and Market: Carefully research your market to increase the chance of success, since you will most certainly have competition with other food carts.
Ordinances and Zoning: Every area is different in terms of where you can park your food truck and how long you can park there. Make sure you know the rules in each location you plan on operating to prevent tickets and fines.
