Sorry it took me so long to get back, other things in life have needed my attention.
Though the specifics of "the place" will involve a lot of players, my vision remains constant. I know exactly "how" it will be. I just do not know how I will get it there. Lucky for me, most of that will be decided by bureauocrats

.
Moving on the "the kitchen", I want to outline what I want (and don't want).
When I browse Ebay, CL, or new concession trailer manufacturers sites, one thing I constantly see, is kitchens designed for people who have never worked in kitchens. Also, I notice that most of them are designed from the standpoint of a 2-3 person daily operation. In my fantasy, my gig will be operated by one person alone, for 9 months out of the year. So to meet this goal, I will need an extremely "fast" kitchen, and in my experience, this is completely defined by equipment, and equipment proximity.
The downside of utilizing higher-grade gear to expedite production is cost, yet that cost would be replaced by labor if ignored, and paying someone else to help me run the rig is an indefinite cost, whereas equipment is a fixed cost.
So I would prefer to spend more on gear, and less on employees.
Looking at typical trailers, I have to say I am unimpressed. Since I cannot post links yet, I'll just send you to the one outfit that I think builds incredibly fast kitchens-on-wheels: Armenco Food Trucks. Just google it.
Those rigs blow me away.
The short list for primary hotline equipment is as follows:
8 burner hotplate
24" grill
24"-36" griddle
48"-60" cold top (sandwich prep fridge)
3 bay steam table
hot food pass-thru merchandiser
giant coffee urn (1.5 -3 gallon)
salamander
convection steamer
double-stacked 1/2 size convection ovens
6-drawer chef base under grill/griddle/hotplate
I hope I am not breaking some unspoken law of roadfood by not including a fryer, but the truth is, I've worked without one for over 12 years and do not miss them one bit.
In my imagination, the hot and cold equipment would be parallel (with the exception of the convection ovens, they can be vented directly and do not require a hood), all of which would be perpendicular to the steam-table/sales window located at the end of the trailer.
Trying to explain what I imagine without pictures or at least drawing is difficult, and in the future, I will try to get up some rough sketches (I am slowly learning google sketch-up)
Ideally, this trailer would be better-equipped than average, and substantially smaller. Though I haven't touched on the prep area, dry, refrigerated and frozen storage, or the ware washing area, these are all also on the list. This particular post is just to describe the functioning hotline, and design goals.
If I could sum it up, my kitchen goals are: speed, efficiency, and cleanliness. I know it sounds pompous, but I am looking to be the pinnacle of professionalism. And that starts with a professional kitchen.
