As long as you're using a secure stock rack, I don't see a problem with it. You would probably want to rig some type of shelter inside the rack in case of snow/rain, though.My husband is saying it is ok to transport a mini cow in a pickup truck bed for 500+ miles. I say not. what do you say?
+1A live moving 800 to 1200 lb cow in the back of a pick up moving around while driving for 500 miles, no way would I torture myself that way.
I don't know how big a mini cow is, but if you haven't hauled a live animal in the back of a pick up I wouldn't advise starting to on a 500 mile trip. Proper stock racks and at least a 3/4 ton pick up would be needed. Todays 1/2 ton cars/pick ups just aren't stable enough for such an endeavor.
