We recommend getting a good, used truck. At this point in the game, you want to minimize your monthy obligations so don't go crazy with a big loan. Check out Commercial Truck Trader for some great deals on quality used food trucks.
You will want to be a part of the bigger food truck community. You will need their support and advice during the start up phase. Joining a food truck association is critical to your success.
It is free to list your food truck and menu on EasyEats.xyz. You can even set it up to auto-track your social media feeds and index them. Posting your new location daily should be part of your startup procedure. Those food trucks that post nearby, will be first in the search results for users.
Once you get established, you can further increase your revenue by adding online ordering from EasyEats. This makes it easy to compete with the brick and mortar food services in your area.
