We have at least 2 FBA teams who use livestock trailers.
Forrest (Forrests Fine Foods) has at least 2.
The larger has small living quarters up front.
Mark (M&E BBQ) has a nice aluminum one with small living space up front.
Both of them seem to like them.
My observations:
NARROW due to sides being inside the wheels. Can really be cramped in the work area, even on a larger one.
They have "slots" on the sides for ventilation.
Those make it a bitch to heat/cool.
OH YEAH--they are livestock trailers on the outside.
So, stop at the livestock inspection stations or you get to visit with the nice guys from Law Enforcement :-D
Ask Forrest about all of that.
But, they seem to work OK for the owners.
