Mine was filthy on the outside when it arrived but it was due to weather. I don't see any point in penalizing the driver, he hooks in up in BC and unhooks it at delivery. He has in own sleeping arrangements in the truck and said they only open it at the border if requested.
These guys are amazing. Mine left BC Wed am, delivered to the Central Coast of Cal Thurs am (how he did it is still a mystery!), slept for a couple hours in a parking lot, and was on his way to Phoenix, AZ for a pick-up and figured he be home for the weekend! WOW! Maybe instead of cash, we should be comp'ing him with some Preparation H! That's ALOT of sitting!
