SPRINGFIELD, MA (WGGB/WSHM) -- Gas prices jumped 31 cents this week in Massachusetts and food truck owners said Monday they are already passing the cost on to customers.

William Osorio left a restaurant behind to build his own food truck and serve his Springfield neighbors, but fuel costs have added a price tag he did not plan for. To keep the lights on and the fridge cold, he needs gas for his generator. To move the truck, he needs diesel. Both are breaking the bank. “I’m spending at least $120 more than I was at this time last year,” he explained. “What used to be about $12 to $14 dollars is like $20 to $2 for the generator without counting on what diesel is.”

That is an extra $120 every week. Osorio calls it a “gas tax” on his dream that he did not see coming.

Roberto Gomez, a truck driver from Arizona, has been behind the wheel for four years. He said the prices are changing where he can afford to work. “We’re just trying to cut out a living for our families,” he added. “And it just stops us from working in other regions, like Washington, Utah, California, because it’s an exorbitant price that we’re paying for fuel.”

For Osorio, the pressure is personal. He does not want to raise prices, but he may not have a choice. “I don’t wanna abuse my clientele, but I’m trying not to do it,” he noted. “But if things keep going this way, I will be obligated to do so.”

Osorio has already added about 50 cents to some of his items. With AAA reporting domestic stockpiles are tightening and no clear end in sight, he may not be done. He did not start his food truck to talk about gas prices. He started it to feed his neighbors. He is hoping the cost of that dream does not outrun him.
