Chains are starting to move into the food truck business. Jack in the Box is one of them. http://www.jackinthebox.com/pdf/JMM_info_sheet.pdf
Franchising is an other option: http://www.qsrmagazine.com/exclusives/franchising-comes-food-trucks
Chains are finding it's more Cost effective to start-up and operate a truck than it is to build a B&M building. Less Hassle from governing bodies, fewer permits needed, etc.
If one location doesn't work-----MOVE!
I predict this will create a MAJOR shift in how chains do business! It also bodes well for Independents.
I'm looking to buy stock in Food Truck Manufacturers!
