when was it last operating?
Are the tires in good shape
Does all for the equipment work
How is the trailer powered
There is a very long heavy gage cord going directly to the breaker box which you plug into local power. You could wire a generator in too.
Will a dipping freezer fit inside and which dimensions would fit?
There is currently a full size refrigerator in there, it could be replaced with a freezer of the same size- maybe could fit it under the windows but would be very crowded- in short, things would have to be removed / changed to fit one.
Has this trailer ever had a three compartment sink with a waste water tank?
