I do hope that you can get it off the ground, but be warned... Around Lexington for example, there is an "Old Boys Club" when it comes to BBQ. Some of them are dying off and/or closing. BBQ (at least in this area) is so overdone, you run the risk of just being "one more BBQ joint". People will compare you to the HoneyMonk, Speedy's, Smiley's, etc... and unless you have something that is WAY better, it will be hard to gain traction.
When I was working at Ecolab, Lexington was part of my territory and I saw a couple of attempts at starting a new BBQ joint and they all seemed to fail. For one, the older restaurants have their smoker's already built to non-existent codes. They are grandfathered in against the new health/building codes. To open a new BBQ joint, you are looking at serious coin to invest in equipment up front just to compete with stuff that's been in use for over 50 years and has paid for itself over and over.
Your choice of food purveyor will make or break you as well. Bigger names like Sysco and US Foods are nice for variety, but typically have such high minimum order amounts that they are hard to work with up front. Smaller more local places like Orells have better prices, but you end up with the same food as they have at every other place in town, so your "special cut fries" look like the ones at Biscuit King - because they are.
It's been said, the best way to make a small fortune in the restaurant business is to start with a large fortune.
Food trucks are trendy now because they appeal to a different market. Used to, a food truck was more of a mobile concession stand which sold pre-packaged sandwiches and cold drinks, usually at a factory or a jobsite. Quality didn't matter because the market didn't have much of a choice in where they ate. When you have 30 minutes to get down from your work perch, get in line for the food truck, eat and get back to work, you didn't get real finicky about the quality of beef in your hot dog. You ate it and if it wasn't hot enough, you set it on a hot girder to warm it up.
Now, gourmet food trucks are popping up in tech parks serving all sorts of ethnic foods to software engineers, business men, you name it. Some of the questions you will need to ask yourself are:
Where am I hoping to set up? What is the demographic of my desired customer? Where is my nearest direct competition? What about indirect competition? What is my target food cost percentage? What makes me any different than what's already out there?
