I ran across a posting tonight on e-Bay that caught my eye.
For a competition bbq cook that's looking to upgrade their operation, this is a nice looking trailer at a reasonable price.
The trailer is a 21 ft bumper pull trailer with smoker capacity to cook up to 60 briskets at one time or up to 50 slabs of ribs! The trailer has a french fry slicer, turkey fryer and propane.
It sounds like a nice opportunity.
Here's some pictures:
Bidding starts out at about $7,000. I don't think you could build a trailer like this for less money.
Here's an enclosed concession trailer from the same folks.
