Food Trucks/Concession

Got some good feed back for my last idea from here so thought I would try again.

Does anybody have experience buying/selling food trucks and/or working is this business? Is it better to buy one ready to go or buy and outfit it yourself? I dont have time to work on it myself so would paying someone to do costs the same as buying one ready? Ive seen fixers for 14k and a couple ready to go for what I need around 25k.

I have the logistics for the business itself wrapped up, but know nothing about the damn truck.

I need: 1) up the code interior w/ 110 outlets  2) fresh, grey, and hot water  3) frig, freezer  4) 9000 watt gen  5) 4 burners  6) at least 2 40lb porpane tank set up  7) 36" work space 8) somesort of warming station

Sorry should say," paying someone to do all the work so would it costs . . . . "

Search around and see what other people use, then search for those kind of trucks.

Or just drive around to some industrial areas and hunt one down who is working and scope out the truck.

Looking for specifics. Costs of fixing up one as opposed to buying a ready to go food truck. Ive checked out multiple trucks and diff. in price can range drastically without visible difference. Whats expensive on the SOB and whats just flasy bs.

i do i actually build and sell on side. i dont know where you live but here in the northeast its a fucked up business they make it so that you have to equipe the trailer like a restaurant kitchen. if you plan on keeping its a good idea to buy. but if you wana do it for a while your better off buying one cause in this economy deals can be found everywhere
