I agree with
@Jim L on this as well. Shippers tenders load to broker, shipper is not a regular over-dim shipper, but has regular flatbed work. Brokers doesn't ask the right questions... brokers a "clean" load to a carrier, who then arrives on site with his step deck, only to find out that when dunnage is used, the load is few inches too high given the step deck height, and broker should have requested a lowboy not a step.. carrier calls broker to advise, broker says I provided you with the dims when i sent the load sheet.... however shipper failed to measure properly, so wrong dims where provided to broker... shipper doesn't understand why its a No Pickup and driver wants to leave as he showed up with the wrong equipment now that carrier has seen the load.
just a complete cluster-f all around, extra charges, new pickup date/time, shipper now has "oversized" freight sitting in the yard until the new trailer arrives... which may or may not be an issue for the shipper. If a crane was rented to load, more costs down the drain due to loading not taking place, due to dims issue.
either way the Shipper and Carrier aren't happy, the broker being the middle man, may or may not take the bull by the horns to solve the issue and keep everyone happy....
Personally i think that most deck carriers are very careful to which brokers they take freight from.... no one wants to put themselves inside a complete mess..... If you know the brokers and shipper, and you're confident that you're getting accurate info, then I find carriers don't hesitate to take over dim stuff assuming the rate is on par.
Most reputable carriers won't knowingly sets themselves up for failure by taking on questionable loads, or loads lacking info from a broker.
