Nothing to see. It's already being done except the lift gate part. You get them to the back and they forklift them off
... trying to get a 3,000 lb tote to the rear of his box truck to deliver, and post it... Would make for a laugh or 2.
Obviously rolling them to the back, to deliver - or to the front at pickup, is NOT an issue.
My problem is liftgate delivery, or heaven forbid, liftgate pickup.
Big R, the video of the class B driver loading the tote(s) with a liftgate should be priceless.
