Had a pin shipped on a pallet from Texas to Michigan w/ABF...arrived with no issues. If..I where to use the Upack service, with a pin..I would load it near the front. The Tractors have air suspension on the rear axle..So, the front of that trailer will ride "softer". You don't want something at the rear of the trailer (no air ride). Abf uses 27' single axle trailers for the upacks..so it is a stiffer ride then lets say a 53' dual axle.
I saw a video of a 55 gal drum of liquid (aprox 500 lbs) on the rear of a 27' single axle trailer with the door open, hitting a speed bump in parking lot at about 5mph, it bounced 2 ft up...(to show the drivers what's going on in the trailer). So, a lot depends on the driver to do things right.
Once the trailer arrives at your destenation terminal they they are very good about a time window to deliver the trailer to your location.
