I think food trucks are awesome. I happen to live in a place where they're super popular, and serve up just about every kind of gourmet, specialty, and ethnic cuisine! 
Yes, food truck are good. They provide food on the go
I understand there's even a reality show -- The Great Food Truck Race on Food Network -- have you seen it?
I don't often watch the food network on TV but  I know food  truck serve good food depending on the vendor
Some vendors actually go on to have their own brick-and-mortar restaurants! In my city, there are several who have done that successfully. Fast food may be common, BUT these guys are way above and beyond that!
Yes food truck are equip long vehicles Some, including ice cream trucks, sell frozen or prepackaged food; others have on-board kitchens and prepare food from scratch. Sandwiches, hamburgers and french fries,
I'm more interested in your own experience -- what would be the ideal food truck for you, in your own words? Maybe a regional street food of some kind?
A small food truck selling ice cream and burgers
Sounds good! There are lots of really great burger places. One popular ice cream one here sells thai-style ice cream that people go nuts over. Definitely not like the kind of ice cream truck I grew up with.
lol. The food trucks in my area sell vanilla flavored ice cream with good beef or chicken burgers  depending on your preference
