I have a Mavron Inc. chassis mount animal-dog hunting box. I was going to use for animal transport/hunting dogs but went a different route instead. My loss your gain, this transport box brand new run about $20,000.00 with the options this one has. Those options are stainless/aluminum construction, drains in every box, air conditioning and heating unit (with controls in cab) with vents in every box, lights in every box along with LED markers on back of box. Storage compartment in middle back of box to get to heating sand AC unit also used for luggage, tools or gun storage. With Removable dividers allowing four big boxes three of them can be divided into 2' X 2' compartments with fourth box having 2 or four small compartments as seen in picture. Please contact 620-271-2221 or 620-271-2220 ask for Andy, Thanks for looking! Trades welcome. Can be put on a trailer
