The trailer is a 2009. It was owned by a gentleman that passed away soon after he bought it. His daughter said he used it about 10 times. She sold it to me in 2014, and I used it half of that summer on weekends at a flea market, and 7 months of last year at a flea market. It hasn't really been towed in 6 years, as I just leave it full time at the flea market, so it's in really great shape.
I personally sold french fries, hot dogs, burgers, philly steaks, etc. out of it. It has a fryer, a 3 foot flat top griddle, 20 inch char broiler, and 2 burner stove top on it, so there's not much limit to what you can sell. You would also be able to remove the char broiler, or stove top if you wanted to add a different piece of equipment like an oven, or a funnel cake fryer, or something else.
