So I want to stay under the federal 18001 gvwr. Bought a new trailer. What it all boils down to is that even though my trailer title and the manufacturer sticker on the side of the trailer says 9150 gvwr the axles are still 5000 each which means the dot can use 10000 gvwr for the trailer. That with the 8800 gvwr of the truck puts me over the 18001 gvwr federal guidelines and makes me subject to trucker rules including logbooks, CDL, placards, name on truck, etc,etc. It all depends on the inspector and what he thinks on that givin day of inspection. I would love to have the tandem 5000 lb axles for durability and a safer longer lasting trailer but the regulation hassles are making me buy and use a more inferior setup. Go figure If only there was a way to solidify the gvwr of the trailer at 9150 as the title states... Any ideas??
