Food truck power- batteries or generator?
I'm reoutfitting an ancient 12 ft. Fiat that, until now, has only been used to sell crappy gyros. I'll now be the road-friendly outpost of our restaurant. My crew and I have set up plenty of restaurant kitchens, but we're all pretty new to doing it mobile-style.
All cooking equipment (grill, fryer, steam table) are gonna run on propane. My question is about the rest- fridge, low-boy, freezer, lights, register. In your experience, is it more efficient to run it off a silent generator (our Eastern European equivalent of the Honda EU2000i), or off deep cycle batteries? Occasionally we'll be able to plug into "shore power", but I want the truck to be self-sufficient.
For what it's worth, the age of the truck and condition of the transmission mean that it won't last more than another 2 years (the purchase wasn't my call- my crew is operating it for an absentee owner), so I'm not particularly interested in building an expensive, efficient system that will pay for itself in 5 years.
